I've often read tarot for myself or others in hotel lobbies - at a table, quietly. No fuss, nobody inconvenienced, and nobody bats an eyelid. Wouldn't even occur to me it's not the right place for it. It's as though I was told it's not the right place for reading a book or knitting. I'm not going to start sweating about some putative fellow guest who might have a wool phobia. I've never seen the hotel management do that either, and nobody ever asked me to stop reading or showed the least bit of discomfort.
Do you allow business people to discuss business in the lobby?
I see that in hotels all the time, business people discussing business in the lobby. Sometimes they are selling and buying coats, sometimes arms, sometimes alcohol, sometimes engine parts. Some of the business might be completely unethical and even murderous. Who's to know? I have overheard guys discussing arms deals in hotels. I am very disturbed by that, but what? Am I going to make a scandal at the hotel and tell the manager that these two bastards are planning to sell weapons that might kill innocents so please, let them do it in the privacy of their rooms?
Of course, in a small lobby with no room at all and where everyone is crowded, the business people are unlikely to want to discuss these things anyway. Likewise, in such a lobby, I wouldn't read tarot - it's just not comfortable, because there's nowhere to lay the cards. I wouldn't knit, either.
This is pretty much the case for all public places, for me. I will read for someone anywhere they feel comfortable as a querent and I as reader. That's about as complicated as I make it. I'm not a rebel - I just live and let live. So of course, if you come to tell me that I can't read tarot in your hotel lobby, I will desist. I won't make a fuss. I just won't come back. *shrug* I suppose as a business person, you have to decide if you are likely to get more "live and let live" types of guests, or uptight born again Christians who object to tarot reading in public; and what kind of guest you actually want. That's a marketing issue, and beyond the scope of this thread (or forum).
BTW, several times I've read tarot in hotels or cafes, I've had staff come and ask for readings when they knock off or during a quiet moment
