That's not practical for any party larger than 2. If the waiter needed to serve martinis to a table of 6, that would be at least 2 and probably 3 trips to the bar. Since good manners dictates that we do not partake until the entire party has been served, my martini is slowly warming up whilst waiting for yours to be brought from the bar. Also walking whilst holding a martini glass from the stem is difficult to do without sloshing martini everywhere, and holding by the bowl leaves fingerprints on my drink and warms up the drink. I know not everyone is going to drink a martini but you get the drift here. There's no way *other* than a tray to transport multiple beverages from bar to table unless you don't mind your waiter looking like the St. Pauli Girl, and I don't mind that in a pub but not in a formal, upscale dinner.

Don't get me started on arm service for plates. I truly appreciate a waiter who can perform arm service for entrees for a party of 4 but for every one who can do it, there's at least a dozen who *think* they can do it but end up with tie, boob, or finger in dinner.
