I lived in the US for over 5 years where Black Friday originated - and it was then just the one day, the Friday after Thanksgiving. Then the retailers got a bit silly and started opening at 4am, then 3am and now Black Friday is spreading across late November.
Anyway, i digress - l lived in Henderson in the Greater Las Vegas area. I used to visit some of the many AMPs (asian massage parlors), particularly Queen Vixen. They did indeed offer Black Friday discounted deals, both on the base fee and on the 'extras' too.
