London has a clever help for what to do with chewing gum. Personally I am filled with righteous fury when I see someone spit that where someone can step on it.
I feel like I may have back slid on patience a bit not getting unduly frustrated by relatively small time delays... not that its ever been a strong point of mine.
It's like I'm a crazy miser sometime; I have a wealth of time in my life and my day, but I begrudge every little nickel and dime, especially when I can easily see how the delay could be otherwise. (4 people in front of me at dunkies? Time to sigh dramatically and roll my eyes! What's up with that?)
