When a bar or restaurant sets out a funny chalkboard sign it’s probably not enough to win over your patronage. (How stocked the happy hour beer and food menu is as well as the number of attractive women meandering around the joint helps you make that decision.) But whether it’s words of wisdom, jokes, or a sad truth — we really are making too many sober decisions these days — these sidewalk chalkboard beer signs do serve an important service. They get you to drink and eat more.
