If I walk into a bar and order a drink I expect them to ask for ID to prove my age. If I walk into a McDonalds and buy a Big Mac I would not expect them to ask for ID to check my age and if they did I would not expect them to photocopy it and give it to Fred to keep in his poorly locked file cabinet.
@grumpygamer Part of what entitles the bar to ID is that there is a very standard and "checks and balances" definition of alcoholic beverage published by the government and not, you know, whatever advertisers and visa and mastercard are currently feeling deserving of a threat to shut down the bar's complete access to the most basic payment services, based entirely on the vibes of whomever is currently writing the most complaint emails to them (usually a fundamentalist religious nutjob).
@grumpygamer Like, I WOULD oppose bar IDing too if the ID was asked of me for any item of the menu that some sunday church fanboy says is an instrument of the devil.
@elrohir @grumpygamer The temperance movement way back in the 18th century were exactly that. I don't know for sure that they're why we have the alcohol age restrictions we do here in 'Murica but I wouldn't be surprised.
