I have a very simple policy of pretending I'm allergic to cash. I hate carrying it anyway, so my policy in the event that I find myself saddled with some old fashioned paper money or coinage, is to give it away to the first person who asks. Whether it is a dollar or 2, or 20 or 200.
I understand this isn't practical for everyone but it is for me and so it is my policy. I don't care if you look like you need it, and I actually don't even care if you do need it. If you're sitting outside in a Chicago winter to ask for it, and I have it on me, you're getting it.
What do you mean by this? Every interaction I've had with the homeless has been, at worst, slightly awkward. I have been lucky to not encounter any homeless people with severe mental instability, but they are pretty rare.
Sounds like you are emphasising the possible bad outcomes and making it seem like it's the norm.
Obviously it's not the norm, even if there are certainly some people out there that can react badly.
I can understand your pessimism, and I'm certain you were not intentionally trying to be negative or make the homeless seem somehow less able to be reasonable, but your comment did give that impression.
If you are struggling to see the good I saw this video recently in defense of optimism that actually gave me a bit of a pick me up. I'd recommend if you have the time.
In the US: Yeah, just about every barbershop I've ever been to only accepts cash. Sometimes they accept card, but there's an extra charge and you have to wait until they find where they put the machine. And generally the barbers themselves seem to prefer cash.
Also, food trucks and food stands? Not all of those accept cards.
There is a little known law in France that requires you to be able to pay a first class fine (about 35€) on the spot. If you cannot you'll be arrested.
As you cannot always pay with a card as not every cop has the required system, that mean you have to carry that arround in cash.
There's the odd off license that only takes cash. My card might not work for whatever silly reason. I usually carry £1 or 2 (separately from my wallet) for the off chance of running into a beggar.
I'm also on my way to the library at the moment, where the foreign language talking class costs £2 in cash.
My spouse was recently asked for cash by a woman when walking down the street. We never carry cash. The next day that woman was in the news for armed robbery of a convenience store.
I am not sure what to make of that. The people asking definitely need it though. You could be preventing them from doing something desperate. But at the end of the day it's your bit of money to do what you want.
