I was having lunch w/2 business associates, in middle of dining 2 of thier associates stopped by table....they greeted by shaking hands...since i was eating I did a verbal nice to meet you.,....later my friends suggested i was a bit rude for not engaging in a physical greeting...I suggested i was not, being rude.. due to fact I was eating lunch....I mean really...WHAT WOULD YOU HAVE DONE????...PERSONALLY i do not shake hands in a restaurant...maybe its just me...???
