The few times I've tried that I get either an odd reply or just get blanked. I assume they get suspiciousn about the request. Like I'm a cop trying to catch them out etc.
I don't just go straight for the throat, so to speak lool got to be subtle
prossie: hi
pumps: hi I'd like to come see you today/later/now, can i have the postcode?
prossies: okay, i'll send it now.
really is that simple.
with all the double booking first come first served bs, they have no interest in knowing what time I'm coming.
