I usually will give change when asked. However.. IF I am nice enough to stop, dig through my wallet and give you some, it is extremely rude to ask for MORE. I gave a man at Mumford Terminal $2.60 in change and he asked if I had a dollar or two more ??? WTF? I think he saw a $5 in my wallet and wanted that instead.
This really gets to me..
---no change for you
