Hello. I'm still a little confused about the walk-in. By "You can walkin on each even Tuesday (2nd and 4th) on each month without appointment." does it mean that I can go every Tuesday? Every 2nd and 4th of the month only? Or Tuesdays that are 2nd or 4th? I know it may sound crazy of me but I still don't get it. Thanks for any help.Ah ok. Thanks!
