There's been a history of people setting up fake ATMs, rolling in looking all official-like, plugging them in without people questioning it, and later being removed for data extraction.

Slapping a "We accept Bitcoin" sticker on someone else's regular gas-station pump and betting that someone would eventually send money would probably be more profitable.
