Didn't get what they solved
I didn't get the whole simple thing :o
Is it similar to scene that a shopper purchases online for self-pickup and while outside mall he calls the shopkeeper that his car is in right corner of the parking? Or, may be that i am in office 9 to 5 and my car will be outside in parking and the guard has the key?
If no, I am completely dumb, sorry.
If yes, they are completely dumb to waste on this research, sorry.
