I have a bad habit of not properly utilizing foreign currency coins when I tour any country. When I pay in bills and get back coins I don't know why my brain is programmed to think of them as change and for the next purchase I would again use a new bill.
Sometimes it is also due to the fact that I don't like to spend a long time on a counter trying to count coins up to a certain amount so just to make it easy for me I would just pay with a currency note that's slightly bigger than the required amount, or use a combination etc. It is also due to the fact that sometimes its hard to get used to the denominations specially for coins on a short trip; they sure do some in various shapes and sizes, whereas on for paperback it is comparatively easier.
I usually bring all those coins back home, they are quite a bunch of them by the end of a trip. I bring them home as a memory or as something that relates to my trip for a long time to come. I am not a coin collector but sometimes when I see that this coin that I have is from a country which i visited when i was a child it makes me feel good. Sometimes my family members take some of them as souvenirs.
The only time I use those coins abroad is on vending machines and lately in theme parks for my kid on toys which operate with coins.
Lately I have been reading about this fairly global practice that all coins should either be used at the airport or given to homeless people in that country before you fly out.
That has got me wondering whether what I do is unethical? I am not a miser nor do I have any use for those coins when I reach home but even when I find a homeless person abroad I give them a currency note instead of a coin.
Is this a bad practice?
