Don't simply refuse to drink with a business associate. This can be taken as a lack of trust or good will. If you don't drink or only intend to have one glass (sip slowly), excuse yourself by reason of your doctor's order/family medical history, and then always stick to your story. Be consistent.

Exchange business cards. Offer one to each person. When giving or receiving, bow your head and use two hands. When receiving, smile, say thank you & briefly inspect it before carefully putting it away in your wallet, card case, brief case, or shirt pocket (back pocket not ideal, but okay in a pinch)
