Long ago when I was a regular at Upmarket Bathhouse in Crows Nest and they had younger (early to late 20s) MLs, the one I saw often once told me how the girls look through the window overlooking the back lane to see what sort of car their favourite clients drove. In those days you could park your car just outside the joint. The girls used to brag about the fancy cars their clients drove and compete who has the client with the nicest car!
Competitiveness is a human condition.
