I could see a couple of possible scenarios here:
1. This is in fact the same day that Kip was shopping for new clothes with Kat, Grace, and Bella and she's getting her big tummy groped by the clerk right at that very moment.
2. The clerk who fondled Kip is still working there, and has had some time to mull over her new kink for a good while, and is about to get her hands on Aika's gut(maybe even Tessa's too, should she appear)
3. The clerk from DWS was fired between then and now, and now a new clerk is working there(only time will tell if they're as much of a pervert as the previous clerk or not)
