Repeated Hopping

I need to reach level 50 to go to the next stage, but I'm only level 19 right now... I was diligently selling pasta today, and when the ad pasta(?) stopped appearing on the pasta stage, I moved to the adjacent pizza stage and saw an ad pizza there...! So, I watched ads for Tomato → Pasta → Pasta → Wheat → Pizza → Pizza, leaving the deliveries to my staff. Today too, the owner (me) is repeatedly hopping between stages. I'll reach level 50...!!
