I encountered one this weekend - SS-I'm-too-drunk-for-the-drive-in.
DP decided she needed a milk shake late Saturday night, so I drove down to Steak and Shake. Love, love, love this place - service is always top notch, food is hot and fresh, never had a single problem and we go there regularly since we've been living here. I order, and notice the girl taking my order is having to get me to repeat myself a lot, and taking a long time to do my order, but I figure it's just that she's multi-tasking since the dining room was pretty full. I pull around, and see what's really going on.
The woman in the white BMW ahead of me is screaming, flailing her arm out of the window and cursing a blue streak. She gets her bag of food, and pulls up about two feet (so she's not in line with the window, but close) and puts her car in park, lays on the horn for a good twenty seconds, and then throws her car in reverse and pulls back to the window without looking (glad I'd waited to pull up!). She thrusts the bag back at the window, starts screaming something about onion rings, cursing again, and waving the bag at the girl at the window. The girl at the window asks her for her receipt (apparently the SS thought she'd ordered one more serving of onion rings than she had). They get it figured out, the SS all but throws her card at the girl at the window, and then is asked to pull forward to the little 'parking' area ahead so they can get her additional order ready. She inches up a few feet, then a few more, then a few more, the car jerking to a stop suddenly every time. She finally gets to the end of the building, puts it in park (not where they asked her to go, but at least out of the main drive through path) and sits there for no more than a minute. I pull up, get an apology for the delay, and pay for my food. I hadn't even gotten my card back when the SS starts honking her horn again, for another 20-30 seconds, then the drivers door opens, the woman leans out and, um, soils the parking lot. She slammed her door, threw it in drive, and took off, squealing her tires. I figured she'd be back around in a seconds, but realized why she wasn't when I finished my order - there were *three* police cars parked on the other side of the building. :-)
