No one at front desk to check in. Sign said please use house phone, call ext. 163. I did, left a VM. A couple mins later, after no one arrived, I used house phone and dialed 0, to see if anyone would pick up. A woman did, and promptly came out to help. Turns out the sign should have been turned around, the proper side said dial 0. No biggie, but an awkward 5 mins or so.
