I just came back from France and the thing I loved the most there is that you can pay with cash on self checkouts, like you just enter the right amount of money to get a banknote in exchange without interacting with anyone
man I wish we had this in Finland, here all self checkouts are card only and if you want to pay in cash you have to go to a cashier

I frequently try to buy things for

and pay with a

or

to then get bills in return and it's kinda challenging because I can get things for like 5-6€ max (if you're giving the cashier a

and then coins so you can get

in return) but with a machine you could just get any amount and then throw coins until you are left with €5 and then enter a banknote
I also got many coins from the new series and apparently those are already common? in Finland I've never seen a single new French coin before even tho it's already been several years since they were introduced

(but I think that the older ones look much nicer, especially the 10-20-50 c ones)
