6. Do not slurp your drinks.
Firstly tell how do you feel when a kid is slurping on his beverages while sitting with you. The same situation takes place if you slurp on your drinks and the other people are sitting with you eating their lunch. So avoid sipping your drinks to the last drop of them and also do scarp your food from the plate, it does not matter how much tasty it. You can order more and can eat it.
7. Make sure that you maintain an appropriate distance from the opposite sex.
When we see someone whom we know in the same place, we feel very excited, and you did not expect it. In such condition, we tend to forget that we are in a public place and we run to the person to give a hug. And imagine, if he pushes you back how will you feel at that time in front of others. So whenever you meet someone known in such places, do the handshake and wish them. Do not run for the hug.
8. Be polite with all.
If you are polite with others, it will help you to build the long relationships. You should keep smiling, nod to your neighbours and also thanks to your driver. These gestures uplift your image in front of others. Everyone notices small things we do or say in front of them.
So try to follow these rules to make your first good impression.
