But how does one make sure that the process of eating and discussing business do not get in the way of each other?

Here is a little handy guide to the rules and etiquettes of successful business lunches:

1) Turn up on time and well dressed.

2) Have a set agenda and do not let your guests know anything about it beforehand unless they have requested it or the situation demands it.

2) Take control and go somewhere where you enjoy the food. Don't ask your guests where they would like to eat but make sure you take them somewhere nice, clean and just as important, convenient for both parties. It is a good idea to take your guest to someplace that you are well known and respected.

3) Always eat slower than your guests. They will then not feel rushed to finish their food. Do not talk with your mouthful. If you absolutely utterly love food, then it might be a good idea to have a sandwich before you meet.

4) Starters are a great idea if you have something complicated to discuss. The time between ordering and the food arriving is a great time to get to know each other and sell your product or service.

5) If you have the time, do not order the main course until you have finished the starter. This gives you even more time to market your widgets.

6) Switch your mobile off! What is more important than trying to win more business? If possible ask your guests to kindly switch their mobile off aswell.

7) Do not drink too much! If you must have alcohol then one drink before the meal is sufficient. Are you there to discuss business or get drunk? In a similar vein limit the amount of alcohol that your guest drinks so that you can have a proper discussion.

8) Common manners apply here as in every situation. Do not eat too much and if you feel like burping or whatever? ask to be excused? and make your way to a private area out of earshot. Be nice to your guest and your waiter.

9) If your guest offers to pick up the tab do not argue. This means that you will more money to spend on other potential customers. If you can not afford to pay pretend that you have accidentally left your wallet at home. I have never used this idea myself, but many people have successfully practiced this last tip on me.

None of this is rocket science but I have seen so many people get it wrong that it is unbelievable. Using common sense and logic in choosing the right venue and how you handle yourself once the meeting begins can make all the difference to closing a sale or losing the deal.
