I'd rather not deal with any inconvenience at all. In a dream world I don't have to swipe/touch/anything, Starbucks just knows who I am and charges the total based on my phone being in my pocket or something.

I don't care how, I just want to get the paying part done in the least possible effort. I'm lazy. At this point I get mighty vexed when I can't just touch my card and have to actually put in a pin number.
