Sex Worker is so Euro-sounding, don’t we still just call them whores?
I think "prostitute" is more accurate. According to the dictionary, "prostitution" is defined as:
the practice or occupation of engaging in sexual activity with someone for payment.
Sounds more appropriate based on the conversations quoted above.
What boggles the mind, though, is that she is referred to as a "blue-eyed knockout" and she'd have anything to do with a schlub like him.
