I'm started out being pretty sure this is a joke, but OP has replied enough that I wonder if she is actually serious.
If this is genuine, I kind of admire your audacity but you seem to have a Trump level of narcissism and arrogance.
Firstly I think you need to get a dictionary and look up what "discrimination" means, because it's quite frankly insulting to use that word to compare your situation to people that suffer genuine discrimination because of their skin colour, disability or other situation. Arguing you are being "discriminated" against because you can't get your daily massage and work from a spa has got to be a piss take.
Whether you are allowed to work from public places like cafes or it needs to be a private location is down to your data security requirements.
But even if you are allowed to work from cafe's (and it's perfectly reasonable to not be, we aren't for example), seriously read the room. You are clearly taking the piss, at least make some attempt to be discreet about it, and not rub it in everyone's face that doesn't have such flexibility.
Optics at work does matter. Do you want to work with people that resent you, and so will make your life difficult, or people that respect you and are willing to go the extra mile for you when needed?
Finally different companies have different cultures, and what is acceptable in one won't be in another. It's perfectly reasonable for them to insist you don't work from a Spa, and equally it's perfectly reasonable for you to then resign and find a company that does support that. Unless your skills are in huge demand, I'd say good luck with doing that....
