I think in the first pay phone call, he convinced her to meet at Long Beard's at roughly 2:30 or 2:45. Perhaps they thought this would be a "safe" place to kidnap her since most bars close by 2. I think she probably told Bri of these plans.
I think she changed her mind, hence all the calls to the payphone. I'm sure she had no clue this was a pay phone and thought SM just had a new number. He probably told her this. Since she couldn't get him, she decided to go meet him, but he never showed.
Maybe SM and TM decided that Longbeard's was not such a smart place after all because there might be cameras. So when HE got back home and called SM, he convinced her to go back out and meet him at PTL.
