So I'm pretty light hearted and I don't typically have issues handling difficult customers. I've dealt with every kind of customer from the most happy to the most unhappy and with the unhappy ones I basically try to find the root of the problem and help them solve it or solve it for them if I can and I know that's kind of a generic response but it's really situational and I would say just being courteous and trying to help usually diffuses most people and even if it doesn't I have pretty thick skin so I can handle it if they're still unhappy but I do my best to make them happy.
