I work in a large well known toy shop and, as you can expect a week before Christmas, it's been very busy today. We have in total 8 tills. 4 "normal" tills, 2 customer services and 2 that are in a specialised section. Customer services serves "normal" till customers and calls them over when they are not busy. The specialised section is mainly for the specialised products, but will often take "normal" till customers when they are not busy.
Today we had people on all 8 tills when it got particularly busy. 10am til 2pm is our busiest time and all tills were covered, or could be covered, throughout that period. Sometimes when it goes quiet one or two people will go and find something else to do, always keeping an eye out in case the tills get too busy.
Anyway, I would say people had to wait 5-10 minutes maximum to be served when it got especially busy. A lady comes up to my till, getting really angry about how she has had to wait 20 minutes to be served and won't be coming back as the service is disgusting and there should be more people on the tills etc. This went on for the whole time I was serving her. I apologised for keeping her waiting, apologised 3 or 4 times to her, said we were very busy and we had all tills covered.
Eventually she leaves, saying first, very loudly "I will NOT be back here"
AIBU to think, if you are shopping one week before Christmas, in a toy shop, you are going to expect queues???
