Groom's occupation at a Fleet (Clandestine) marriage of 1744.

It is a tricky one, more of the page would help to compare the writing.

Thanks, everyone. I think it is Gentleman's Servant. Glad that was cleared up. I had considered "Gent", but the text didn't quite match up and I wasn't sure the need for a Gentleman to use the services of a jailed clergyman at the Fleet prison.
For those pondering the remainder, it is St James Westminster (where he lived and had at least 2 children by Jane).
Much obliged for the input.

All I can see is West Guildford I can't find the occupation

The Guildford suggestion is ingenious, but if the letter we have made out to be "S" (in Serv[an]t) were an "f", I'd expect it to look more like the "f" in "of" on the lines above and below - with a long descender and a crossing.

Moreover, checking out St Francis, Westborough, Guildford, it appears that the church was built in 1933 (see http://www.achurchnearyou.com/westborough-st-francis/), and I have a Crockford's Directory from the late 1950s which suggests that it wasn't a parish in its own right even by then. 19th century maps show that area as just countryside, with no development at all, so I think we can be confident that there was no such church or parish in 1744.

Josey is correct in Reply #8.  It is a standard contracted form of Westminster.
