I don't want a chirpy, chatty person behind tils when I'm buying stuff, I don't need to know about your cousin's hernia leave me be,

I don't however blame people in retail for being miserable when they have to deal with the twats that are about these days, it's not in their job description to be happy, as long as you're getting served, who cares what mood they're in?
