I had 90 euro left over after the trip. Forgot to exchange it at the airport, brought it to the bank, they sent me to Travelex. They were offering me $70ish for it. I get it that they buy back exchange rate is higher than the sell rate, but more than 30% difference? No thank you.

Teller was pleasant and cheerful, but you might want to numb yourself against the exchange rate shock with a large slug of alcohol prior to entering the establishment.
