Sorry about your wholly avoidal brush with danger. Shame you weren't lucky like the other punter recently who had a lovely lady turn up, chat for a while then mutually agree that she politely leave without taking any money.
NEVER ask a strange SP to come to your home, especially any of the advertised sub 150 outcall only services touted around the classifieds and listing sites. If you must receive an outcall do it at a hotel, not even an AirBnB.
Otherwise just get in an Uber/Addison Lee and go for an incall.
If you're feeling in the need but can't be arsed to leave your home call up a booty call or stroke one out for free. If you're still in the mood in the morning then book an incall with a known SP.
