Was talking with a property owner who was renting apartments during this time and he told me prices were paid based on the rate of that instant as they were literally changing by the minute or hour. He never left home without his calculator. As soon as he was paid, he’d run as fast as he could to change them for dollars.
These days and thanks to the DNU allowing cancelation of payment obligations in whatever currency, if it got that bad, he would just say pay me in green-backs and be done with it.
Let the tenant deal with going to the cueva or doing a MEP transaction and getting the cash out from the bank teller window.
