LMAO, I'm from Torrington. I've been known to frequent that Starbucks on 44/202, though I don't actually care for any of the products the company produces other than espresso and cocoa. I'm aware of the "Simsbury Rolling Stop" because it's caused at least two accidents while I've been in the car. GO northwest CT.... Miros is also from our lovely corner of hell. Just don't eat at the fucking Friendly's around here. I think they hire from the "I just got laid off from a real job, so now I'm a disgruntled bitch waitress" pool.
As for treating your servers right, I think the same courtesy should be extended to customers in terms of "having a bad day". If you get the regular dick, yes, feel free to spit in their latte. I work at a Circuit City, where I really go the extra mile for almost every guest, regardless of their treatment of me. If I recognize them as assholes on more than one occasion, I just stop greeting them. You'd be amazed how fast your managers recognize you when you are super nice to even the most frustrating customers.
My rule for tipping is the bill divided by 6, plus or minus any good/bad behavior on the servers part. My biggest pet peeve in being served is ignoring the table between key interactions. The easiest way to get the tip upped for me is to fill my glass before it's down to a quarter full. Little extras like that go far for me. My favorite tip that I ever left was a single dollar bill attached to a note reading "The other 9 you would have gotten were given to the donation bin at the front counter, maybe next time you'll remember to check up on your guests instead of having a smoke." (we could see her outside smoking whilst 3/4 of the people at the table were completely drained of drinks and the ketchup bottle was empty, and she didn't come back after giving us the food till it was time to give the bill and clear the plates)
