Escort refers to a form of sex work in which the sex worker visits the customer (hotel, private apartment) - in contrast to salon or indoor work. Accompaniment is often offered for occasions (business lunches, events), with sexual services only following afterwards.
Escort activity is legal in Switzerland and is subject to the same registration and tax obligations as other sex work. Safety tips: Buddy system (inform backup person), hotel name & real name of the customer in advance, pre-payment via Twint/Cash upon arrival, no consumption of drinks ordered by the customer.
