Brilliant business idea, but beyond that...the service is functional! I've never had a problem with mint locker and I love the convenience of having dry cleaning at my place of residence. Often than not I am not afforded the 9 to 5 convenience that most have; my schedule can get sporadic and sometimes I'm leaving a few days after I fly in, and mint locker's turn around time accommodates that for me.
I also like the little VIP Baggie they issue after your first order...and get this, you even get a mint...get it? MINT locker! Haha ;)
