Can’t speak for other countries but in the U.S. counterfeit bills are usually used to buy something cheaper at a store and receive real money back as change from the cash register. e.g. Pass a counterfeit $100 bill for a $20 purchase & hope that the cashier accepts it and gives you back $80 in real bills from the cash register. Think of it as a more roundabout way to take money out of store cash registers, that’s the main purpose of counterfeit bills.
I work with a business that has a storefront and people do come by every week or so to try to pass counterfeit bills. Usually the staff knows enough to check $100 bills but every once a while they miss the counterfeit.

Oat milk is fine, or even just drinking it black unsweetened.
Though in the last few years I’ve gotten into the habit of having my cold brew concentrate with Ripple Unsweetened. And before that was using Silk Protein unsweetened… it was sort of Silk’s version of pea protein drink, I think it got discontinued haven’t seen it anywhere. Ripple goes well with my coffee… Silk’s version was especially good with coffee, I’d still be buying that if it was being sold anywhere. Silk’s was a bit creamier and thicker than Ripple so it sort of gave the coffee some extra flair if that makes sense.
For these type of drinks I mainly try to find unsweetened with a similar nutritional profile like dairy milk e.g. it should have a decent amount of protein, calcium, vitamin D, etc. Most oat milk I’ve seen doesn’t have that so I usually don’t buy it, it’s more something I’d use if I’m at a coffee shop or someone’s house.
