I dunno, in much of southern Europe it's certainly not expected that people will be there to the minute even for one-on-one meetings. Probably not an hour late in that case, but I don't think anybody would bat an eye if you had planned to meet at a coffee shop at 2:00 and someone showed up at 2:15. You'd just get a coffee and read a book or the paper or something. (Being exactly on time, and being angry if someone's 5 minutes late, is seen as a stereotypically "German" sort of thing.)
