Most of the girls give excellent service and honour the 30 minute time they are supposed to stay.
50 euro is quite a decent compensation for what they offer and actually quite modest compared to what is asked at other places.
Your main concern will be to avoid the sharks that try to cut short the 30 minute with a minimum of effort.
PHG management is interested to know which girls do not offer what is standard.
Too many complaints will mean they are no longer welcome at PHG.
