The 1963 Broadway musical "She loves me" is set in a Budapest parfumerie in 1934.
In the play, every time a customer leaves the shop, the employees sing a short jingle:
Thank you madam, please call again. Do call again, madam.
I was wondering why the verb "call" is used, considering that the business serves casual customers that don't book appointments.
Does "call" have a special meaning in this historical, geographical or gergal context?
