I don't think we've done this topic before.
On my recent trip, I used a lot of different ATM's.
I find that it's nice to have smaller bills when traveling. No one wants to accept a 20 euro bill for an 80 euro cent baggette first thing in the morning and often they will simply say no. I've seen automated ticket machines that purportedly accepted 20's but in fact would spit out anything bigger than a ten. A fifty is virtually worthless unless you are purchasing something that costs two thirds of that.
I found two machines I liked, one offered 20's, 10's and 5 euro notes as options, so I could get some smaller notes. My favorite offered 50's, 20's and 10's but let me choose the bills. I got 60 euro in all tens.
My least favorite was HSBC. When I asked for 50 euro, it spit a 50 out - I could sense the machine laughing at me as it did it.
Sadly, I didn't pay attention to the brand of cash machines I liked. Can anyone recall the banks where they received smaller bills or an option to choose the bills they wanted?
