I worked in a grocery store (in the US) back in the day. People complained about the smallest stuff -- that I wasn't as conversational as they wanted, or that I wouldn't process their coupons in the order that they expected, or even in one case that I wouldn't help them steal from the store.

Maybe 1 in 10 complaints I received was even remotely close to something a sane human would be even mildly inconvienanced by (and even for those I can't imagine ever caring enough to spend my free time complaining to a grocery store manager). It wasn't just me or just that store; management had an entire formal process passed down from the corporate office for figuring out which complaints should contribute to evaluations and which were spurious. I never had less than 10 complaints per quarter and only two of those were mentioned in my evaluations over a several year period. Other cashiers had similar numbers. Interestingly, friends who worked at non-grocery-stores encountered these sorts of things far less often.

I'll never understand the psychological reasons for why people behave like this. It's probably the same reason people troll. But I do wonder whether it's a US-specific phenomenon wrt grocery stores specifically.
