I mentioned this on another board a while ago but I think the story is worth repeating.
A couple of years ago I was working as a forklift driver in a warehouse. My lift was running low on power so I went to switch out the battery. The batteries on these things weigh several hundred pounds and so you need to remove/place them with a special mobile sled which is a little tricky to drive.
I had taken the old battery out and was replacing it but was having a bit of a tough time grabbing the new one off of the rack on the wall. After six or seven tries, I still hadn't gotten the sled lined up perfectly with the rack. The maintenance guy came by and said to me, "Are you taking twenty?" I was pretty surprised. I hadn't thought that there were any other gamers working there.
Turns out there actually
weren't any other gamers there. The batteries are numbered. I had been aiming for #20 and he noticed that I was having a tough time of it. I tried to explain the concept of "taking 20" which he listened to with a polite but confused smile.
