Yes, when u pay for a certain time(30 minutes) ushould enter in apartment at 4 pm for example and exit at 4.30pm. But many guys think half an hr appoiment means half an hr 'action' witch is not right. is difficult to finish EXACTLY in half an hr as nobody stay nd watch the clock to see '' i have 7 min left so i have to make him to cum in 2 min and then in 5 min he have 3 min shower and 2 min to get dressed' nobody can do this as u cant exactly predict how long will take that why i always said and considered half an hr like a quick service as time flying very quick and u know in the back of your mind u have just 20 min to satisfy him (minus 10 min dressed undressed shower and maybe a briefly chat to no use to much time ) then u cant exactly know when to finish foreplay and start to concentrate to make him to cum as for some guys take longer and for others take 1 min) so my advice book longer time to can relax and enjoy your time together and the escort to not think about 'u will not have enough time to finish him ' and subconsciously rush the things .
