I am in Subway ordering my $5 footlong veggie, it's not really busy but the customer in front of me is on her phone. From the sounds of it, she was speaking another language. The Subway worker was trying to be patient asking her the same questions over and over again about her sandwich. I starred at her, trying to give her the none verbal - "can you concentrate here?" but it did not work. I passed her up and got my sub. I told the worker helping me that that is very rude.
After I left I thought, can a worker refuse to help someone who is on their phone and not paying attention? Should I have said something since the workers did not feel like they could call her out on her rudeness?
