One of my last tables tonight was four people who seemed nice and friendly enough--even though they wouldn't shut up for me to take their order. One of the guys had his legs stretched out into the aisle for everybody to trip over. When I brought their drinks, he had shifted so he was facing mostly forward, but still had his legs stretched out as far as he could get them. That meant, of course, that I had to stand farther from the table and stretch to set down their drinks.
Legman had ordered a drink that comes with a martini glass and the metal shaker. I set the martini glass down and reached back up on to the tray for the shaker so I could pour his first glass. While I was pouring it, he went and set his menu down--across the silverware and taking up as much spare as it could. There was nowhere at the edge of the table for me to set down the metal shaker, so I tried to very carefully stretch over his legs, and the first foot of occupied table, to set down the shaker--while still holding three drinks on a tray on my other hand.
Yeah. Didn't work. None of the four people tried to take the shaker I was obviously struggling with, and when I set it down it was uneven ... and thus the table became a lake of pomegranate booze. And when I tried to catch it, the drinks on the trays started wobble, and one totally fell over.
Legman's jeans got splattered in raspberry tea, but nobody else got splashed, luckily. Of course all the drinks had to be replaced, the menus that were doused in drink had to be thrown away, and basically it was a huge freaking mess. And it wouldn't have happened if my table hadn't been oblivious to how difficult they were making my job.
Luckily for me, they were cool people--I got my best tip of the night from them, actually. But too many times I've had similar situations where people got all offended. It's similar to when I'm walking by tables and somebody gestures widely and knocks food out of my hands. People just need to be a little more aware of their surroundings.
