Sorry he said he gonna call immigration ... N I'm student . What u think he is just scaring me or he really going to call them. I mean can he call immigration n complain about me without knowing I'm legal or illegal to do Kam .

i think he is just trying to scare you!! lol how is going to complain you without knowing your work status!!

happened to me couple times!! i even googled the irs number and gave the customer and asked him to make a fool of himself!!! idk whether that customer called or not bt i had no problems!!!

 No need to worry bro...If he was going to call , he would call to police right after the argument. Has happened to me in the past, but it differs on case to case basis. If you think he is really going to call, try to alter the shift, specially, if he is a regular customer, try not to work during the times he visits the store.

Why do you fight with customers? You are in a fragaile condition so be nice evrbdy it will make your job easier.

 If your in a customer service related field, remember "Customers are always right" no matter how dumb they sound. Your not paid to judge, argue or discuss with the customers but to serve them during their visit. Guys, just mind your business and do your work.

 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..
