client lunches?

Ok folks i need some help with this one!! i have been hearing the excuse "i can't eat healthy because i have client lunches" can someone please explain this to me?? i will plead my ignorance here, is a client lunch when you go to lunch and talk business? is it rude or offensive when you eat with a client to choose healthy food? do you go to places that don't serve chicken or fish? i would think a business client would envy the fact you make healthy, smart choices and maybe you take care of business the way you take care of yourself. Then i hear "well when you eat out at client lunches everyday (really?, everyday you have client lunches?) its boring to eat chicken salad. Ok first who said you have chicken salad everyday, second I think being unhappy with the way you look and feel is boring AND depressing. I believe, and these are my beliefs so you don't have to agree, eating for excitement needs to be chosen wisely, weddings, birthdays, baby showers, date night with spouse, you get it right? If you have client lunches "EVERYDAY" and you can't eat healthy 90% of the time then boy oh boy ....
