You got it! Try this for yourself: Build 20 x Burger restaurants, collect income from them every 6mins18secs as soon as the yellow $ appears, do this on all 20 for at least 30 times (3 hours) but preferably 100 times (10 hours) - that will be 20x30 = 600 to 20x100 = 2000 collections. Collect income from nothing else during this time, including tapping on no quest bubbles.

Absolutely guaranteed you will see your Income DROP.

Even better, upgrade all 20 to Level 5 first, and you will see your Income DROP even FASTER!!!
