reminds me of a good one of mine over spring break: the bartenders at our hotel in Jamaica. By far the worst service I have ever seen. You could be the only one at the bar and they would totally ignore you for 5-10 minutes while they puttered around with their back to you. If you called for them, they'd just get more pissed. If you tipped them a few times, it'd be a tiny bit better but it was still slow and you would still get the death stare. I decided that down there you tip to get somewhat less sh------- service instead of to reward good service. If they only realized that most people reward good service they'd make a lot more $. We had an all inclusive deal, but after a few days were buying our own bottles of cheap rum and making our own drinks.
Overall pet peeve: Idiot drivers. Many have already given some examples like the 4-way stop, people cruising in the left lane, etc. I'll throw in another one the people from other states (not WNY) that freak the hell out at any sign of snow or adverse weather. It's just some snow flakes blowing around on dry roads buddy, no need to go 35 mph with you blinkers on. Freakin Ohio drivers suck!
