Returning a car with Avis is quite convenient. Sometimes, young staff members will recommend upgrades, which can be worthwhile. For example, I paid an extra $10 per day to upgrade to a GMC Yukon, and it was totally worth it. However, if an older staff member helps you, they often lack the knowledge to offer any useful recommendations. For instance, they might class a Ford Expedition the same as a Chevy Tahoe, but the Expedition has a noticeably smaller cabin. While the Ford might handle better, if I cared about handling, I wouldn't choose a large vehicle. Most in-office staff are nice, but the people at the exit lot, whether Mexican or Chinese, act pretentious. That's a definite negative. You're just a parking lot attendant, there's no need to act superior, especially to Chinese customers. Because of this, I will never rent from Avis again. They are the most expensive and don't offer better service! Avis mostly lacks Chevy Tahoes!
