what was the british comedy in the 90's about a department store run by kooky people?

Are you being Served:

Set in the antiquated Grace Brothers department store, the show followed the OTT antics of its staff.

Leading the troops was the dowdy Captain Peacock (Frank Thornton), a city gent with a penchant for pomposity.

Head of ladies fashion, Mrs Slocombe (Mollie Sugden) sported a different hair colour every week and continually harped on about her "pussy", while assistant, Miss Brahms (Wendy Richard) was the literal butt of a slew of bottom-pinching antics.

Meanwhile fussing manager Mr Rumbold (Nicholas Smith) watched on in bemusement.

The stand out character, however, was Mr Humphries (John Inman), a camp, senior assistant in the menswear department, who became infamous for trilling his catchphrase, "I'm free!".
