I've also been through the Metro Lounge about two dozen times, and enjoy having a place to hang out between trains. I've never had really bad service there, and sometimes they are downright friendly.
The last time I went through, a 40-something man seemed to be in charge, although wandering around the room rather than working the front desk. He said he was a "retired" Amtrak conductor who got tired of riding the rails and posted for the position. He told me all about the new lounge, although admitted that there were still a number of undecided issues. He said there would be showers and some sort of bar, either cash or "gasp" with a drink token or two. It is so rare to see something on Amtrak actually get better.
My greatest amusement is the announcement system. As anyone who has been there knows, an employee creates an announcement by speaking loudly into a phone, clearly audible through most of the lounge. Then he or she hits a button and the phone replays the announcement in all its glory through the loudspeakers. You'd think after a few days on the job an employee would be ready to just make announcements directly. I don't think I've ever heard one erase and re-record one.
Looking forward to the new lounge, but also may give the Legacy Club a try next time I'm in town.
