Sometimes it is hard to tell if a customer wants your card or not. I have been out of cards and had someone request my card. Card etiquette is not universal but it is bad form to poke your card at everyone that passes your way. Handing multiple cards to someone to pass around is a bad idea and a waste of cards. If someone is that interested in you they will request a card or multiple cards as needed. A beg no no is to just leave a card laying around in hopes of someone cold calling you…never happens. Art Falcone gave me multiple cards. I threw them away.
