For Laughs :D - My ride with Mohammed

A bit lengthy(understatement) but interesting encounter i had yesterday...
After field supervision in Wa i had to head back to Tamale (for my non-Ghanaian readers, these are cities in the Northern region of Ghana)
So as usual i call up the car rental for a driver
Im giving a driver named Mohammed
Through out our phone conversations (before actually meeting up) Mohammed had been VERY VERY professional. I instantly liked him for that.
Then it was time to pick me up
As soon as Mohammed saw me, he giggled and asked if i was Dagomba
Of course i am
We set off for our 5-hour journey...
Just then he turns up the radio on full blast and i kindly request it off
Then we bumped into some of his old friends, he stopped to chit-chat
I really didn't mind until he comes over to the car and says to his friend
'Don't you see she is pretty?' (Awkward!)
We continue our journey
About an hour into the ride (at which point im lying in the back, with my eyes closed tryna nap)
He comes to a stop and signals to a stranger,
The man approaches and Mohammed asks him where he is headed, he replies, Damongo.
Thats when he turns to me to ask if we can give this man a ride
Well saying No! whiles the man is looking on will just make me look like a wicked witch
And well its Ramadan so maybe Mohammed just wants to give a stranger a FREE ride
I agree
We continue our journey (Im dozing in and out of sleep)
Then i hear Mohammed tell our new friend (thinking im asleep) how he is only offering me a ride.
He apparently bumped into me in Wa and offered me a ride to Tamale cuz we live in the same area, plus he's known me from way back. He couldnt just leave me stranded like that (LOL!)
We get to Damongo.
And guess what?
Mohammed charges this man a fare (so, no, it wasn't charity and no i didn't get my share!)
Lol!
At this point i finally doze off to sleep until we arrive in Tamale (Thank God!)

One question i really wanna know is
How did professionalism get thrown out the window so fast?!
Was it realizing after we had finally met, that a) she is young so this one is a 'small madam' or b) realizing we are from the same tribe, Dagomba, hence identifying with me as his 'Peoples'.

Either ways, I'm still baffled :)
