Just walked into T-Mobile with a friend for a new sim card. The atmosphere was pleasant besides a rude sales associate named G***. He displayed no courtesy and gave off a vibe that we were wasting his time. Whoever is head of business should have a chat with this employee. The rest of team was charming. G***'s attitude is weighing everyone else down. G*** needs to treat every customer as his most important customer. I didn't want to show this sales associates full name for respect of the company.
