I work for a supermarket and was working on the checkout earlier. I was serving an elderly lady who had a massive pile of vouchers and was trying to sort them out and yes, it took a while. However, my issue was with the customer behind her in the queue. She huffed and puffed, kept pushing forward and sighing and then started moaning about how she "thought this queue was going to be the quickest", she was "in a hurry" "had to back in work in the next 5 minutes" "the shopping wasn't worth losing her job over" etc, etc. I know its annoying when you chose the wrong queue, and it's annoying when people don;t have their vouchers ready and take longer than you expect but I don't think there is any need for the fuss she made. All I did was kind of laugh it off and say that I always end up choosing the wrong myself, in fact I normally warn people not to queue behind me, because it will be the slowest moving one! I could see that the elderly lady was feeling uncomfortable so should I have said something stronger to the second customer? Or should I have told the elderly customer to hurry (not that I would ever do that/ accept that I should have done so
)
