All Check Cashing, Port Jefferson Station NY

Come here a lot. I have a boss who writes checks out to "Cash". Been cashing the same types of checks for months here. For some reason, I had to argue with the guy who tried to decline my check for about 5 min. He then tried to tell me he's doing me a favor and will do it this once. Afterwards he asked my last name, looked me up, and said "Oh, I see we've been cashing your checks. " So why argue instead of looking me up in the first place. Very unprofessional. I told him I won't be here when he is working anymore due to him not knowing what he's doing and not doing his job properly, but instead argued with a customer.
