Baileys best before date
Considering even the possibility of litigation, that is, if someone were to get sick and then make the correlation, I think the wiser move as an entrepreneur would be to simply give the stuff away before it expires. I'm sure the regulars would enjoy it. Plus, if you think quick enough on your feet you may be able to come up with a way to use the giveaway as a promo for something that actually brings in revenue ...perhaps a DIY Irish Car Bomb with Bailey's provided at no charge, worth the sale of Guiness and Jameson's.
