If I have the right person then I think he had a variety of jobs. On his marriage in 1902 to Elizabeth he is a "waiter", on William Stanley's baptism he is a "shopkeeper", on his son Graham's in 1908 he is a "traveller" , on the 1891 census he is an "assistant groom", and on 1901 census he is a "fruiterer salesman: on his own account", on 1911 census he is a "carter - brewers" and, as you say, on Frederick's baptism he is a"chauffeur". If they are all true then at least you know he was a worker!
