multi serve multi serve multi serve.
also acknowledging customers as soon as they get to the bar, and if you cant
take their order straight away, then just ensure them you know they're there
and what order people will be served in.
i like to multi serve alot though, if you dont feel able to do this, take a
couple of orders while you make one, then make the next, obviously if one
person only wants a bottle of beer then you can do this straight away for him
it takes 4 seconds etc, one more happy customer.
hope this helps
