Which brand?

Here's a short one, but one to be noted as it is so ridiculous.

Early one morning we have a lady walk through our door, bringing back a laptop we had lent her. My colleague signed it back in as he usually would and the lady enquired if we had any other brand laptops.

My colleague said that no, we didn't.

"Oh" replied the woman. "I was told you had loads of brands."

"No, sorry these are all we have."

"Well, that's not very good." She said "Other brands give you a much faster internet connection."

The office fell in to stunned silence, the lady, completely oblivious to the absurdity of her statement, shrugged her shoulders in disappointment and left.

Where do people get these ideas?
