Don't even worry about putting people's names on the plastic mugs!(as most any
marker will not come off of this type of plastic.) We have swithched to
plastic mugs in the bar I work at and they seem to be working fine. They have
two downfalls though, they dont hold the cold as well as galss and they
scratch and cloud with time, where a glass one woulden't. I'll check with the
bossman and see where he got his mugs
