What do you grab when hunger overcomes you in the middle of shopping, running errands, etc.?

I usally finish all of them and est after i finish them.
So it gives me motivation to finish them, so basicly i reward myself with eating, playing video games etc.

Sweets. I know that it's bad for me but everything else I've tried as an alternative to "bad sweets" tastes disgusting and isn't as satisfying. I also reach for it when I'm bored but I just can't make myself do something else.
