I ordered some tempered .25" thick glass for a coffee table. The coffee table design has a small shelf and a large top.
The glass shop etched in their logo on the small piece. Apparently, since the glass was small the company assumed it was for a window and intentionally etched their logo on the glass.
Not a huge deal, they'll re-cut the glass for free.
Anyway, be sure to spec out 'no logo' or something similar to avoid this problem.
Cheers,
