I don’t believe you should be looking at women, talking to women, or handing things to women! When I go to a store where there is a chasidish or yeshivish man at the register he puts my change on the counter and doesn’t even drop it into my hand.
If there is that much pritzus on the train and in the city, maybe you should consider that you are traversing in the wrong sevivah and go elsewhere!!!! Give the cards to your wives and find something else to do in your spare time.
