I'll pretty much say the same thing: Customer service jobs suck for us. People don't like to be inconvenienced, or feel they're targeted for it, and don't like the rules of where they're shopping to stop them. The real rule of the trade is, "Keep them happy within reason, but ask a manager if something feels over the top." Frankly, they should nix the whole 2 strawberries bit, but they're corporate goofs trying to save money where they can.
As for job hunting, look for stuff that requires a minimum of social interaction.
