Hey Andy, hope all is well...
I used to tip Door Men/Concierges well - more so Concierges of course... Then again, I used to tip everyone well. I always just assumed everyone else did as well and they made hell of money. Even when I have been in situations where it was a treat to go out and eat at a decent restaurant because times were tough... I always tipped well beyond normal when given good service with the right attitude.
I have also walked away from tables leaving nothing for a tip before too. All depended on the person's attitude to me, which the majority of the time was atleast worth 15%
