I have never posted a bad review as I generally think 'why damage someone's business?'. In this case, it is in the interest of the paying customers.
If a W/G offers genuine punters, a bad service and has a poor attitude. She doing most of the damage herself.
IMO, sites like UKP, help punters when researching a W/G for a punt. Reviews can paint a picture, of what her attitude and service, is like over time.
Although initially polite, provided services on the profile, Sandra near Liverpool street is very robotic, disinterested, and fractious, which ruined the atmosphere and eventually I said 'don't worry about it' and quietly left.
What services were on offer or used?
Did you get the full amount of time booked, and if not did you ask for the difference (if any)?
What was her reaction, to you leaving?
Do not waste your precious time and money on this person, it will be a disappointment.
Punting some times is about taking a chance.
If you don't like what you see, hear or feel. Walk away without handing over any money
