I like clear, detailed, unambiguous instructions.
There is a well reported SP near me who asks anyone to enter the random word from her profile and if they don't she ignores the communication. When I see her she shows me some of these messages, and people that txt her 20 times without the word, and she sometimes just winds them up by chatting with no intention of meeting them.
A lot of SPs reply by text with
Ethnicity - NBA?
Proposed Date / Time
Services requested, length of service
Confirm price
Size and girth of tool
Disabilities - can you use stairs
Allergies - pet hair / peanuts
preshared - word
