A two-time loser!

...I would hope they were at least smart enough to stand next to the bar to estimate how tall it was and then find bar stools just a bit shorter than that.

I would think you're still hoping too much, though this is what I would do. How hard would it be to go, hmm...the bar comes up to my hip/waist/shoulder/appropriate body part, so the stool should come up nearly that high?
