Dollar General complaint: Manager is rude

I go there a lot! The mgr. Allan is not professional or friendly he brushes you off if you have a question or need help. He acts like you’re bothering him, he’s mad all the time or acts like it never smiles.. It is also a FedEx drop off there. I took a package there on 1523 I had the code in my phone for him to scan which he didn’t do. I said I have the code he just shrugged his shoulders said I don’t need it. Says in a tone not nice your
phone number. I gave it to him he walked off. I said don’t I get a receipt he turned said you’ll get it on your phone keeps walking. Well anyway FedEx driver just left my package on my doorstep. Allan never printed a label for my return so it came back to me. My friend goes there also and has complained about him. Needless to say I won’t be going to this DG anymore! He’s been rude to me for the last time! Allan needs to take a class how to work with the public.
