"Englanders' grease"? Is that an underhanded insult regarding the origins of people who visit Sidmouth...? As an "Englander", I don't think ever been called on

"Englanders' grease"? Is that an underhanded insult regarding the origins of people who visit Sidmouth...? As an "Englander", I don't think ever been called one in my life! I think its main use is pejoratively in "Little Englander", which I'd normally assume "Englander" was shorthand for. Perhaps it was selected to avoid "men" in "Englishmen"? "Tourists'" may have been more correct (and gender neutral)...
