I'm afraid I was an SS associate the other day.
I didn't want to be an SS, and I was trying to reduce the SSness of the situation, but couldn't.
I was checking out at the grocery store. I didn't have too many items, so it shouldn't have taken that long. Rather unfortunately, the checker noticed that I was buying some dog treats. The checker jumped on this and decided that she needed to show me photos of her son's dog on her phone, only her phone was taking forever to come up and she wasn't checking items while she was fussing at her phone.
It took probably 10 minutes more to check me out than it should, because the checker was DETERMINED to show me photos of her son's dog. It was insane. I kept trying to push things along and say that I'd see it some other time, but she would NOT drop it. There were probably four people behind me in line by the time I got done. I felt horrible, but I don't know what more I could have done.
This same checker gave me heck for buying a container of cleaned shallots when they were out of normal shallots. She said something like, "Hey! The delay is all your fault for buying these shallots instead of the normal ones! I have to have someone go find the price of these rather than just looking up the price per pound!" I mentioned that they were out of normal shallots, but she didn't really listen to me.
I think I will avoid this checker in the future.
