foreign load
n.— «Servers also learn to cope with what in pub parlance is called a “foreign load.” That’s an inebriated customer who has been kicked out of a bar up the street but managed to pull himself or herself together enough to walk into your place and get served again.» —“At the bar, driving home the benefits of moderation” by Erica Noonan Boston Globe (Massachusetts) Sept. 5, 2007.
