Do you want a quick way to know if the bar you are drinking at is a respectable establishment?
Check if the pint glasses have Greyhound Bus advertisements on them. In case you are drinking your beer late at night on a weekday and think “I need to get out of town, now. By bus.”
I also want it noted that the advertisement is not a sticker; the ad is painted on. From the bar I was in, I can only assume the marketers hit their “target market” right in the bullseye.
