Agree totally, often when paying with cash I get looked at funny as well. Im not old, old but I still like to save up a change collection. Spend notes and save all the coins in a 25-litre water bottle. No idea where in the world you are from but here in the UK, we have coins up to £2 which is $2.47 American so it can add up quickly. My cheat is if the total is within 50p of a note, i buy a pack of cigarette papers to make so i need to break a better note and get more change. 🤣
