Discreet and parlour don't mix
A good indie girl MIGHT only see 2 or 3 guys a day most par!our girls see 5+ each shift say 3girls 2 shifts a day = 30+ visitors each day and possibly 100 - hardly discreet
Having said that just grow a pair and knock on the door like you aren't a criminal and you'll b fine - probably wise not to shit in your own bed though
