I work in a gas/convenience store with a soda fountain. The prices for each size of cup are posted right where you grab the size you want. Had a lady bring a soda up to the counter and it went like this: M= me, C= customer
M: Hi, that'll be $1.10
C: Oh, why that much?
M: It's 99 ¢ plus tax
C: Oh, it said 66¢ back there (pointing at the fountain) (We don't have a 66¢ soda)
Me: I'll bet the 99¢ sign is upside down.
She looked crest-fallen and took her soda back to the fountain, poured it down the drain and got a 79¢ drink. Then she took it to the other register, wouldn't look at me as she passed me.
Evidently she didn't notice that the ¢ sign was upside down and on the wrong side of the 66.
