Family used to own stock in a local ski resort (publicly traded), all shareholders were entitled to half price on lift tickets and some other perks. It was a great way to save a bit of money, get a dividend, and have a voice on any future expansion plans at the annual meeting.

Edit to add: Seems even Disney did offer perks as well to shareholders, https://www.disboards.com/threads/do-you-own-disney-stock-wh...

Plenty of companies offer shareholder benefits without ripping off your rights as a shareholder.

The big cruise line companies will give shareholders on-board credit, Berkshire Hathaway has sales from their subsidiaries at the yearly meeting, Intercontinental Hotels has discounts, etc.

One of the customer service backdoors for some companies is to buy a share and contact investor relations if you are having a problem.
