Customer 32 (asshole)

So customer comes in, wants to start up service. Well the first thing I do as always is find out what they want. Give a quote. And make sure theres no confusion. The last thing I want is to get yelled at for doing a credit check and "not giving all the information" or "misleading" them. And in my line of work, not to sound racist but asians are the worse, especially indians. And we went through the entire thing step by step. They told me they went to a kiosk in the mall and from experience they lie. So their telling me oh they quoted me less. They quoted me this and I kept telling them those figures are wrong they are designed to make it sound good then your bill hits and its high. So I explain to them and theybwere convinced no they quoted me lower, I want to hear its lower therefore the lower quote must be right. So I spent 30 min talking to them and they finally agree to start service up with us. So I do the credit check set everything up even get a supervisor to credit them back an extra $80 on their first bill and we get to the very end. All agreements signed. No cost today. Low monthly cost. All I have to do it hit ok and I already have concent to but theybwere talking in another language so I waoted because I dont know what they are discussing. Then out of no where the wife is like wait I think we need more time to think. Its going to be to expensive in the short term. Im like what?? Wait to expensive in the short term? You cant get the money for your bill? She said yeah we need more time. Im like.... first off your $155 up front cost is $0. Your first bill supose to be around $150 and second bill around $150 will be $0 but its to expensive in the short term. And thos is why at my job the stereotype indians are cheep is 100% true. Again not to sound racist but indians are cheep. Blacks are loud and black women normally very pissy blaming everyone but themselves.  Whites are either quick and easy or try to be a business man and penny pinch everything thinking they are always right and if you dont give them what they want well ill just speak with your manager. Dont get me wrong not everyone falls in here but so far for indians im 100% success rate.
