Answer: It's a show of sophistication. Working class men in pubs and clubs (north, south, and London) typically drank from beer mugs. By insisting on a thin glass Jack is making a public display, of socially distancing himself from the average beer drinking peers, showing he has refined himself from his working class roots.
This is 180° wrong. Thick pint pots with handles were just becoming fashionable when this was made, by ordering a straight "thin" glass he is opting for traditional over trendy.
This is 100% rubbish. The new design of the dimpled mug glass in the 70s was a continuation of the fluted mugs of the 1920s. Northerners, particularly Yorkshire, preferred their beer in jugs, not straight glasses.
Not true at all: everyone I knew in the 70's and 80's always preferred their beer in a normal "thin" pint glass, not the thick, chunky dimpled things. Rightly or wrongly, we always felt it tasted better from a proper glass.
