leave the drama for yo mamma

why can't people leave their drama at home?
i work with a guy that is normally a super barista buddy. he works really hard, he gets along with everyone (including customers), and you used to never have to worry about him leaving you a crappy shift.

sounds like he's got his beans in order, yes?
well - no.
barista buddy turns into super-whiny barista baby when it comes to his girlfriend. he's moody, he's listless and he's in the backroom every ten minutes trying to call her and beg for her forgiveness.
it doesn't matter that all his friends have told him this girl is no good. it doesn't matter that his managers have told him his barista baby behavior is affecting his job, and impending promotion. none of that matters because he's "in looooooove!"

now, i wouldn't normally be bitching about this except for the fact that my schedule is being directly affected because of him. whenever girlfriend puts the pressure on him, he calls out on his shifts, or gets some newbie to cover for him, thus making my job harder. or if he can't call out, he spends the whole shift acting like his dog died and is totally useless.
some might think, "well, he's going through a tough time. don't be so hard on him." but can i just let you know that when his grandmother died, when his aunt was in a coma, and when his brother was in juvie he was a real trooper. sure, he wasn't chipper but he did his job and he did it well. so why can't he leave the drama at home now like he did before?

barista rant: it's bad enough you didn't order your drink correctly, but don't yell at me when i put whipped cream on your frappuccino! so, you forgot to tell the register partner that you didn't want whip. ok. so why are you yelling? and really, can't you just stop sucking the straw when you get to the whipped cream? it's a stinking frappuccino! the whipped cream won't melt into the drink! it just moves down the inside of the cup as you inhale your frappuccino. why, when i offer to scrape the whipped cream off the top, do you give me a sour look? you're the one who didn't order correctly and now you want me to make you a whole new drink because this one has whipped cream cooties? grow up!
