PNC Financial Services Group

I've been banking at this Bank in Greenfield on murry avenue, some months now and I've always use the same check the same check that I started my account with my work check, I went up there last month and one of the white Tellers act like she didn't want to cash my check so one of the black woman tellers told her how to do it, I cash my check but I deposit my money in three different accounts that I have at PNC she didn't want to do it, well today I went in there to deposit $2, 000 and it was a different Teller young black lady and she went and asked the same white lady who cash my check before and put the money in my accounts can she do it in the white lady told her no I don't know if this white lady has a problem with me or she doesn't know how to do procedures at the bank but it makes me feel like I don't want to bank with PNC I don't want to put my money in PNC I don't know if she has a problem with me I don't even know this lady personally I don't know if it's a race issue I don't know but how come you can cash my checks one day and not the next, there the same company checks, I feel like PNC should look into this because if she's doing this to me I know she has done this before
