Yeah, it's been a lifesaver in the past. Definitely an art to it.
Donkeys ago i was trying to work out where a massage burd was located in a development
I had the look of a punter, two phones one on maps [a combo of google, apple & waze trying to work out where to go

]
The other doing texts & me talking to myself cursing like FFS blah blah

Two [i reck EE] fittie SPs [not the burd i booked] spotted me from a 1st floor window waved to get my attention & beckoned me over
They lifted their tops to show great racks
I was pondering what to do & the SP i'd booked then called me to give me directions & i went along with this
I'm still wondering what might have been spur of the moment stuff

No call or even 10 secs later & i would have ditched the one i'd lined up
The last few posts on this thread reminded me, happy days
