Wells Fargo Bank

Hoping this rating will stay! Opening a joint account with boyfriend this morning. A checking & savings account. Starting it with a large check that is their check with the hopes of getting it cashed first with no problems because he has to get to work by 10, I wouldn't think it would be a problem due to the fact the check is their own but we don't have an account yet. Does anyone know how they are regarding to cashing checks? If he has no problems then when he gets done with work between 2-3, we're going back together and opening the accounts, just no time this a.m.!
