I have met Polish chippies, electricians, labourers, bricklayers, plasterers, gardeners, teachers, prostitutes (both male and female), baby-sitters, models, shop assistants, businessmen, cabbies, body-guards, security staff, designers, bus drivers, clerical staff, secretaries, spies, library staff, baby sitters, petrol attendants, tramps, musicians, artists, nerds, web-masters, mini-cab drivers......et al et al.....
But
I HAVE MET NO POLISH PLUMBERS!
Postscript:
I think the bulk of the population of Warsaw now resides in London and the Home Counties. The Catholic Church will be pleased.
