I know that everybody has a back story and very few of us have it easy, but if you work in the service industry, service is your most important product!

If I come into your establishment to enjoy myself, please do not tarnish my enjoyment with your attitude. If you are busy, that's good for business and should make you feel positive.  

If you are the bartender at a sports bar and I come into your establishment and ask to see a specific hockey game which is about to start, don't make me wait while you clean the bar and show me attitude when I politely ask for my game again 15 minutes later!

It's a sports bar and that's what it's there for. Don't call me "Brother", please just do your service job!
