I have at least two - but I do not want to get in the mood from the first one.
So back to the time when I was working in a bakery as a seller. Where I come from some pasteries have different names in different regions. As if this was not already irritating enough, sometimes the same name exist in different ragions but mean other pastries.
This was the case for the pastry in point. Let's call it X - a filled pastry. In other regions it's called Y, but in our region Y is a smaller pastry, unfilled and roled in cinnamon and sugar.
A costumer strolls in "I would like to have 5 X."
My colleague is packing up and ringing her up "4 $, please." This is already a good price.
She lost it, saying that they were not 4 $. We checked and it was the correct, reduced price for that amount. She argued that 5 X should cost 2.50 $ and that we needed to sell it for that price. After a little back and forth my colleague asked why she thought it was that amount and she pointed at the little tag in front of an empty display row (left to the row of X) 5x Y for 2.50 $
My colleague apologized profusely that there were no more of Y and she had not yet had the time to take the tag out. But X were in fact 4 $ - pointing to the tag directly IN FRONT of the line of X.
The customer threw another small fit and complained, but in the end I think she took the pastries home (like I said 4 $ was already a good price). I think she said something about talking to our superior, but honestly they were used to irate costumers and as long as we stayed polite would just apologize again.
My colleague was crushed, having been berated in that way and looked at me as if she wanted to apologize again. I calmly pointed out that the woman knew perfectly well that her pastries were called X in this region and could have just ASKED for Y, making things easier for everyone. And that my colleague did nothing wrong as the last few of Y had been sold earlier in the line - and making people wait to remove a tag is really bad service.
