I was in a Asian grocery store today at half past one. It is Korean owned. There are three people eating their lunch out of take out contains, chomping away behind the counter. There is also the owner's son, but he is not eating, just working and ringing in sales.
His friends, or whatever they were, were Caucasian. They do not work there either, so it's not like they had to be have a quick bit to eat before working. There is always somewhere to eat.
As a customer, it is kinda disconcerting to have people chomping away behind a work counter, who do nto work there, and look like slobs in a crammed quarters. I purchased my veggies and left.
It seems unprofessional to me.
