Wells Fargo

i m banking with wells fargo in kings mountain nc.i m a small business owner, working by myself.so i use drive through some times to do deposite.one girl always work at drive through, she is very nice means very nice.i talk to manager about her.we always appreciate good service.while i was talking about thay girl to the manager other womanwas i did not say anything about her.shesaid something like why i m not good?she was made o n me .since that day she dont even smile at me.
now today i went to the bank to deposite my money.i m a smal business so i dont have big big deposite.i have deposite for 2300$.wheather was bad.no body was in drive through, so i went there to make deposite.she denied my deposite saying limit for drive through is 2000$.even though she was free she was not doing anything she denied.why?2000$is big deposite for wells fargo?i see that usually when no body is in drive through they help front.i was there for fifteen minutes she just sit down in the chair.she dont have customer all that time.i know she is older lady.she can not work fast.why she is in drive through?or if she dont want to work drive through just work in the front.
i think she did that because i m indian?if u dont like indian people just tell them dont come here, we wont bank with u guys.ant way i m gonna leave the bank.i dont like to do business with some body racist.
