If you didn't pay your taxes on Wednesday, here's hoping you at least got something for free. Several restaurant chains offered giveaways on Wednesday. Hard Rock Cafe, for example, gave people people who took the stage and belted out a song a free “Local Legendary Burger.” If you said “Taxes Shmaxes” to the cashier at California Tortilla locations when you placed your order on April 15, the chips and queso were on the house.
