I've used self-checkout 4 times in 4 different stores in the last week and had a problem 2 out of 4 times. 50% success is not success.
Every store is different:
- Do they weigh stuff in the bagging area?
- Do they scan produce bar codes?
- Does it take cash, or card only?
- Is there annoying lag? (Frequently, yes!)
- Is it going to scan something twice because I hovered, because it lagged?
Also, let me ask:
- Why isn't there space for my cart?
- Why am I juggling stuff in a tiny bagging area?
- Why do the bagging area hooks suck?
- Why is there only one attendant in the stores that have really sucky systems?
- Why are half the self-checkout kiosks closed?
Self-checkout is not made for shoppers. I prefer self-checkout, but I wish good systems were more common.
