Got this little tip from my co-worker, just thought I'd pass it along.
If you're serving liquor at your reception, it may be a good idea to get "special bride and groom" shot glasses. The idea here is to keep your own shot glasses behind the bar, and ask the bartenders to pour only a teensy bit of alcohol (if any at all) into your glass. It's your wedding and you may be a popular person to do a shot with. Might help to remember it! LOL
