That’s assuming it’s a large increase in the bill for no reason.
It’s easy to justify having a larger bill with more traffic. “A retail store isn’t going to complain that they need to buy more stock after selling more stuff that’s just a cost of doing business.” Meanwhile it can be hard to justify a capital expenditure just because traffic increased.
you can rest assured that even the largest company will come looking for the person responsible for increasing an expense by that large of a percentage. So maybe it doesn't come out of your personal checking account but you will certainly pay for it.
