False advertising?
How about Pizza Hut and Domino's brochures that promise you "Unlimited Large Pizzas - $6.90 pick-up" but when you read the small print you find that that price includes only Meat Lovers, Hawaiian and Supreme (the pizza for undiscerning pizza eaters) and all the others have a $2.90 surcharge. Which seems to negate the word "unlimited" in my view. (I know, they are meaning quantity, but still...)
