Accepting a drink from a stranger, even an awesome stranger
If some guy you've never met comes up to you, introduces himself as "Trevor," and then hands you a fruity drink in a plastic cup, you need to ask yourself a few questions. Number one: is this "Trevor" a "Trevor" that you know? Number two: could the drink be laced with some kind of drug? It's best to err on the side of caution. Not all dudes named "Trevor" are douches, but you have to admit, many are and that's kind of weird. The stranger offering you a drink might be awesome, but why chance it? Buy your own booze, let a friend buy it for you or be there to watch a bartender make it.
