Once you've been to the different plasma donation centers in Vegas I think you'll learn to appreciate how smooth and efficient this place is. The prescreening line, the line for the physical and the line to get on the donor floor all have stanchions and tape to manage the people in line and there's a security guard to watch over them. No one's playing their music in line and no one's trying to cut the line.
Once you're on the donor floor the employees do talk but they're working and talking. They're also fast, friendly and efficient and I never waited more than a couple minutes to get stuck ( and all of them did a great job inserting the needle - little to no pain and good placement ) or waited long to get disconnected. No one's allowed to play their music or talk on the phone so you're not surrounded by people making all kinds of noise. If I came at the right time I could be in and out in a little more than an hour.
Compare this to Oct..P where they do all this wrong and it can be a veritable nightmare getting in and out.
