Not sexist in my experience. Except that we have the Euros here.
But it is also obvious to me that women tend to spend a l-o-t more time at the ATM. Fishing out the purse from their handbag, trying to find the card, considering which slot to use and how to put it into the slot, considering about the amount of money, pondering whether to have a receipt or not, putting the card back to purse, taking the money and the receipt, putting them to purse, putting the purse to the handbag and then, maybe then they might move away from the ATM.
When men do the same, there is no hassle whatsoever. The card is already prominently displayed when going to the ATM, put it in, push some buttons, pull it out and walk away happily.
Basically the same machine serves three men during the same period of time that it takes to women to go through the whole episode.
