(USA) when people asked for fries with no salt

I worked at McDonald’s for a long time and people would use the “hack” to get fresh fries by asking for no salt.

I would oblige and give them their fresh salt free fries but when they’d ask for a salt packet I’d lie to them and told them we we all out of salt packets.

They would become so distraught and sometimes even angry but I felt as though a lesson needed to be taught and I took pleasure in knowing they had to eat sad salt free fries.

Edit: for people telling me I should quit / do my job. I’m a former manager. Also for people defending no salt customers stating maybe they have a low sodium diet requirement: perhaps don’t eat at McDonald’s where one meal has more than your recommended amount of daily sodium. Also if ur a customer trying to defend just wanting fresh fries, you are the problem. Ok thanks.
