where I live in NYC there arent any Subways thusly I never usually get the pleasure of riding on it. Ive done HB numerous times and simply purchase a $9.20 Metro card for $8 and then give the clerk at the booth .80 to add it to the card so its an even $10 for a roundtrip tkt. Cant put less then $1 on the card with a CC
1 time I didnt have any cash and they let me go out with only the $4.20 left on the card instead of $5
But whats the deal with getting a 15% bonus on $7, how does he go about doing that?
