Sorry but £150 ph for a 40 year old thai, must be a piss take. She would be lucky to get 50 quid and a bag of crisps for an overnight in Thailand.
Delusional to the max, some of these WGs.
Most of the Agency Thai girls are 30-40+ so not at all out of keeping with the set of SPs we've been generally appreciating for at least the last 5 years.
What's delusional is thinking that all such SPs have to conform to your criteria set.
If we're talking paradigms then a fit 40-something who knows how to perform is way more desirable than any number of out of shape, work-shy, clueless 20-somethings with poor judgement.
