Here's a simple trick to avoid getting all 50 euro bills.... Withdraw an amount that's not an even multiple of 50!!

240 would do the trick.

When we tried that we often got four 50€ bills and two 20€ bills. We found it was purely random, sometimes we got our requested amount in all 20€ bills and other times we got as many 50€ bills as possible with the rest in 20€ and 10€ bills.

If you are concerned, buy 100 euros before you leave, then use european bank ATMs for the rest of your cash needs in Europe. Make sure that they are bank ATMs--just as in the USA there can be non-bank ATMs that have unpleasant charges--and poor exchange rates.

As to the mean-spirited statement "Also if one is worried about a few dollars in fees, they really should consider waiting till they can afford a trip before they take one.", a few dollars saved here and there can make a difference in the ability to travel for some people.

Using ATMs after arriving in Europe; walking instead of taking public transport; taking public transport instead of walking; staying in hostels or one or two star hotels instead of 3/4 star; dining on pizza instead of at a Michelin starred restaurant; drinking a glass of house red instead of a bottle of the finest and tap water instead of bottled--it adds up, and many people enjoy this sort of money-saver trip just as much or more than some people who choose to spend more lavishly.

Paul - The statement was general, and not directed at all at the OP as he never suggested the fee was wasted money. Seeing as English has a very poor second person plural I used the word "one"
And I still say, if ONE is worried about a few dollars fee to get 100E pre trip pin money, then they should consider waiting.

"And I still say, if ONE is worried about a few dollars fee to get 100E pre trip pin money, then they should consider waiting."

OR at least take a shorter trip. I have known people to be so short of money that they couldn't afford to go up the Eiffel Tower. Better to travel for a few days less, than stress over money.
