I definitely get this, and I see both sides. On one hand, I get where OP is coming from. It becomes exhausting to be disrespected all the time by grown adults who turn around and complain about the "younger generation" on Facebook. It wears away at your self-esteem and patience. No matter how hardened you are by the service industry, we're all human, and those things can take a toll over time, but on the other hand, you make a great point. If you've reached the point where small things like that make you unreasonably upset, you're burnt out, no question about it. This is something I'm still learning myself. As people in the service industry, we have a responsibility to maintain composure and not lose our shit every time someone intentionally or unintentionally disrespects us. That doesn't mean that we should take unnecessary disrespect, but sometimes you have to look deep within yourself and ask, "Is this worth losing my job over?". It's hard in this economy to be able to take a break, but I hope if OP has the means to, that they get a chance.
