Has anyone else been approached at Bell Square by young men and asked strange personal information?

I was walking around Bellevue Square by myself this afternoon and was stopped by a man named “Dave.” He was very friendly, asked me all about myself, where I was from, how long I was staying here, how old I was, my job, etc. I’m (22, F) rarely, if never, approached by guys in public and I just found it super strange. He hugged me after our conversation then just walked off. He also had me text his number so we could ‘plan to go for a drink’ so I tried to reverse phone number search him. I’m from small town eastern WA so I’m not sure if this is like a common ploy by creepy guys to get young girls into bad situations, as a mall would be the setting for this unfortunately.
