sometimes u can't be nice.. what if they want to run off with 80 dollars of gas, what if they're bagging candies and other goodies in their bag pack, what if they say they gave u 50 dollars bill when they only gave u 10 dollars bill... not all customers are civil and sometimes u have to be firm ...whatever happens happens for your own good dude.. even if u are sent back to Nepal u will be much better situation rather than working an animal.. so let ur destiny work for you , don't worry too much..
