Yep, used to get it all the time when I was a salesman many moons ago..

I used to cover GEC / Plessey (or GPT as they were known back in the day) who had two big sites in Beeston Nottingham and Edge Lane in Liverpool, both now sadly shut down , and both of which were not the most salubrious of areas back in the early 80's.
And many a time with my regional boss we'd go for a post customer visit pint and the sight of a couple of white blokes with short hair, short sleaved white shirts and ties walking into a back street pub not far from the sites used to send the locals into a lather...
