Barty knew the area well, including most of the coffee shops. Some of them were less kind about shagging on the premises, but if he really wanted to return to one that was a bit...strict, a few good memory charms were all that was needed. Barty got what he wanted after all. A few muggles weren't going to stand in his way. And currently, he had a link for trying to find Vera no one else probably had - or was using at least. Barty doubted Bells talked with her sister, and as for Cissy, well, Barty didn't ask.
Andromeda was being shifty with her answers, no doubt so as not to give him any advantage. But he wasn't going to change. Every coffee shop had a chance she had gone there. It was better simply not to have her affect his game so strongly over so little a thing. "If not, you're in for a surprising treat," Barty smiled, moving completely at ease, "How do you like your coffee?"
