Do you allow kids to call for a ride using the business phone. Or do you have a pay phone and make them use it?
OR do you do neither and not give them a way to call if they don't have a cell?

Or????

I dial the number for them to make sure they don't call long distance. It's a rarity for them to ask here anymore since every 10 year old has a cell phone. How did we ever grow up without them?

Point out the pay phone first. If then they have no money. ( even if they have $1 and the concession is closed the vending machines make change) I will dial the phone for them to call their ride.
