Feedback on the United Airlines Detroit Office in Michigan

I’m curious to know if anyone here has dealt with the United Airlines Detroit Office in Michigan. I’ve read that it provides support for bookings, flight changes, and baggage issues, but I’d like to understand what the real experience is like. Are the wait times usually long, or is it fairly efficient if you visit during certain hours? I’m also wondering if the staff are friendly and take the time to guide travelers who might be visiting for the first time. Any tips, personal experiences, or advice would be really helpful. Sharing your feedback could make it easier for others who are planning to visit the office soon.
