"Excuse me sir, do you need any help with those?" "No. Leave me in peace so that I may choose the blender that is destined to adorn my kitchen."
"Ok, but just so you know, that particular model has five speeds, stainless steel blades, and a three-year blade wa-" the clerk started to say.
"Silence," Merlin commanded and gave a wave of his fingers at the clerk. "I told you that I do not need any help."
The clerk clutched at the place where his mouth had been only a moment before. Now, the bottom half of his face was smooth. The clerk tried to speak, but all that came out was a panicked moan. His fingers scurried back and forth where his lips had been. His eyes were wild. He stood a moment longer before rushing off. The old wizard paid no attention to him.
"Now, Alton Brown used a Blendtec blender on his show recently," Merlin said to no one. "He is a wizard for the modern age if I have ever seen one. But I don't know if the Blendtec brand is right for me. They do have some rather nice hand mixers. I wouldn't have to worry about storing another big piece of equipment then. Perhaps someone can help me."
He turned to where the clerk had been standing and saw that he wasn't there any more. "Where did that fellow go? You can't just abandon a customer in the middle of a sale. What are they teaching these kids when the come in for a job? I shall have to summon help."
He whispered a brief incantation and raised his right palm toward the ceiling. A burst of greenish flame shot up ten feet. It was only a moment later when a security staffer came rushing around the corner.
"Not you again," the bulky man said. He dropped the fire extinguisher to his side, but did not let it go. He knew better, after the last time.
"Ah Mr. Reynolds. I need help finding a blender. It will be used for many things, including in the preparation of potions and powders that could bring world rulers to their knees and propel man into a new age of enlightenment.
"I don't know how you got in here but you need to leave, now. We told you last time that you weren't allowed back in the store, not after you made that refrigerator come to life and it almost ate that old woman. You also scrambled all the store's computers, trying to pay for your washer/dryer with some kind of glowing rock."
"The Rock of Quixil is worth far more than any washer/dryer combo, even if they have a one button wrinkle release setting."
"I don't care. You need to go. Now. How did you even get in here in the first place? I didn't see you come in and I've been at the doors all day."
"I can alter my shape as easily as you put on a new pair of pants." To prove it, he changed himself into a giant newt and then changed back.
"Look, you've got to go. If you don't leave now, I'm going to have to call the police. And from what I've heard from a buddy I've got on the force, you don't want the police coming around here. They're still pretty mad about when you changed everyone's tap water to wine and all those kids got drunk and were falling over each other in the street."
At that point, the young clerk who Merlin had silenced came running around the corner, still making panicked sounds. He had scratched up the bottom of his face, and there were thin lines of blood running down his chin. He saw the security guard and ran up to him, pointing at his face and trying to yell.
"Now that does it," the guard said, "I'm calling the cops."
He stormed off to the store's main office. The young clerk looked at Merlin, his eyes pleading.
"Oh, fine, you may speak," Merlin said and waived his hand again. The man's mouth reappeared. "What can you tell me about the Blendtec blender here? I saw Alton Brown using one on TV, but I just don't know if it's right for me."
The clerk screamed and ran off.
"Must not be a fan of the Blendtec blender. Maybe I should go with the KitchenAid."
