In a cultural function, some seats were reserved for the distinguished persons. But an ordinary spectator wanted to have one of those reserved seats which were empty. He said to the guard, "Can I sit there?" The guard replied, "Yes, you can. But you may not."
What did the guard mean by these modals : 'can' & 'may'?
26The guard was being a smartass, which is surprising, guarding duties usually doesn't attract people with high-brow attitudes and a proclivity for splitting hairs over usage of the conditional mood over the subjunctive. – Stian Yttervik – 2020-05-07T14:06:21.853
along these same lines, also be aware of the subtle distinction and overlap between may and might : both can be used for both possibility and permission, e.g., "I might go to the store later" vs. "might I have another cookie?"; and "if it isn't too crowded, I may go to the movies" vs. "I may not have pets in my apartment"; someone being as pedantic as this guard was could play games with "may" and "might" – landru27 – 2020-05-07T14:26:01.810

@StianYttervik Alternately, the guard was answering the question in a strictly correct manner as one would expect from institutionally trained people (I'm assuming royal palace type guard, not rent-a-cop). Being aware that the spectator would be likely to misinterpret his answer the guard also provided a translation set to his level of ignora..., errr, understanding. ;-) – mcalex – 2020-05-08T12:28:23.533
@StianYttervik You mean, nobody with a high Liberal Arts education works as a guard? You wish ... welcome to the gig economy. – Kaz – 2020-05-09T15:07:06.357
If you may not sit somewhere, then the only way you can sit there is by disobeying the denial of permission. That's why can has replaced may; we operate under the assumption that will honor the permission or denial. Or else, we do whatever we want and don't ask for permission! A compliant person regards can and may to be the same; lack of permission renders them unable to do it. – Kaz – 2020-05-09T15:08:44.790
