And I totally agree; you probably don't need too. I however usually get a latte w/ soy milk which takes a bit longer and so I tip.

Clearly someone didn't get their cup of coffee this morning...

I couldn't agree more. I haven't tried the app yet but as a regular bux customer I only use cash so I can give them a tip. I always feel bad using a CC because there isn't any way to tip them when using plastic.

It sure would be nice if they had some cool tipping options on the app. (Such as, "Round up to the nearest dollar", "25 cents", "50 cents", "75 cents" and a dollar.)
