Well, there's this one friend who often offers to pay for my drinks at mobile on the run when we stop there. He'll be like, "I got it!" and I'm like, "...fine. I'll pay next time though." And guess who ends of paying next time? Not me...
Gosh darn my generous friends. XD
BTW this is a joke, I don't really find it annoying. It's the closest thing I could find to something annoying tho.
