Stupid

I went to buy something today.

The sales assistant said, referring to a price list, "We're doing a special offer this month. There's a 30% discount if you buy 6." I could see the same sheet of paper that she was referring to, and I could see another column next to one headed 30%. It read 50%.

So I asked "When are you doing a discount of 50% if I buy 6?"

"Er, I need to check with the manager."

A few minutes later:

"This price list is out of date, we don't do the 50% discount anymore."

I didn't buy.
