Phyllis constantly going to Crimson Lights

I don't know about you, but if I knew someone had framed my son for murder, broke into his apartment and planted evidence, publicly harassed my teenage granddaughter, and dumped my son's dead girlfriend's body in a river . . . I would not continue to frequent her coffee shop on a frickin' daily basis! Like, what the hell, Phyllis? WHY does she keep spending money at Crimson Lights, contributing to the success of Sharon's business??? Make it make sense!
