I think it was the first time ever I returned a beer, but I had a really good reason IMO. I was not wearing my glasses and they only had 4 beers at this Cuban restaurant. One was an Amber Lager, one a Pilsener. I knew something was weird about the tap sign, could not really read it from a distance, but I tried the Pilsener anyway. Got back to the table, sniffed the head, it smelled like grapefruit. I knew immediately I would not like it. Sipped a couple times...this is NOT a Pilsener. I don't care what they label it, it's not, period. Brought it back, told them look, I don't mean to be a beer snob, but this is not a Pilsener, it has grapefruit or something in it. They said yes it's a Pilsener, look at the sign. OK gloves off. They are the bartenders, they should know this stuff. I said again, I don't mean to come across this way but there is a Purity Law of 1516 (only 4 ingredients allowed in a real lager, and a Pilsener is a subset of a lager --- water, hops, barley, yeast). Anything else added automatically disqualifies it has a Pilsener / Lager. One of the bartenders immediately walked away like that was some seig heil remark, the other nodded 'sure, whatever', and then offered a different beer. Took the Amber Lager and this time it was real. I don't know what they teach in bartending school, but one thing they should teach is the difference between a real beer and a crap beer. There is a big difference, popularity of the crap beers aside. Any decent bartender would know that something labeled a Pilsener that had added grapefruit is a joke, it's not a real beer. Period.
