During the entire run of Are You Being Served? the staff of Grace Brothers is only shown outside of the store in five different episodes.
In Closed Circuit, the staff leaves Grace Brothers to escort Miss Brahms to a fancy restaurant as part of a scheme to trick a wealthy suitor.
The Erotic Dreams of Mrs. Slocombe finds the staff attending an opera in yet another scheme designed to make Mrs. Slocombe stop obsessing over Mr. Humphries.
In Monkey Business, the gang visits 10 Downing Street to meet with the Prime Minister.
The staff visits Mr. Humphries at his second job in a theater of ill-repute to watch their filmed commercial gone wrong in The Night Club.
And in the final episode called The Pop Star, the staff is shown at the BBC Television Centre performing alongside Mr. Spooner.
In The Hold-up, the staff calls Mr. Rumbold at his house, but he's technically the only person shown outside of the store. (So it doesn't count.)
