It can be even more ridiculous than that, sometimes. A friend of mine started a food-related business that required him to install stainless steel plumbing in his rented commercial space. Fair enough. But he then discovered that tenancy regulations prevented the landlord from "upgrading" only one unit. So, my friend had to pay to to have stainless steel plumbing installed in all the units (a six-figure expense) even though none of the other businesses required or even wanted it.
