Who'd you explain this story to if you had missed you exams? There exams would have gone. Thankfully, that didn't happen. But waiting on end for a complete money transfer is another level of frustration. I sometimes leave the good, take the salesperson's number, she ask for a refund when they get it.
Would I even have been able to tell the story well enough to make it make sense?...good thing all went well.
With giving the salesperson your number, that works, too. Sometimes. However, not all of them would let you go. If they begin to narrate their ordeals about failed transactions and some customers unwilling to take their calls or send the money plus with fake alerts, you'll just pity them.
That's why I like to move around with cash walahi. I no get strength laidat.
