If it's anything like using the 50 euro bill in Spain, it's hard to use them in everyday transactions as usually places don't have enough change (or want to loose that change) for 50 euros if you order a coffee for example.
Right, but if at the start of the day you've got no €20s but 4x€10 in your till, that could be change for 4 customers with €20s - or a single customer with a €50.
And a policy of "no €50s" is simpler and clearer than a policy of "€50s accepted only if we have at least 2 €20s in the till" which means customers won't know if they can pay until they reach the till.
The reasons a small business might not keep a large float of €20s in their till is probably obvious!
I use the 50 EUR note in Spain quite often (every week) without any problem whatsoever. Obviously if you are gonna pay a 1.30 EUR coffee with a 50 EUR note you might be asked if you have a lower one...
That problems happen if you try to use the 100EUR one and obove.
Guess it's very location dependent. In the middle of Barcelona/Madrid, people won't have any issues with your 50 euro bills but in villages scattered around (mainly my experience is Catalunya), it's hard to find a place willing to give you change on a 50 euro bill if you're only paying for something that is around 10 euros or less.
