Burger and fries

So you might be completely and totally stressed out about how much money you owe in taxes this year, but at least you can get a free burger on April 15.

In order to ease Tax Day’s annual blow to American citizens, a slew of restaurant chains are serving up free and discounted foods on Wednesday. But read carefully: There are some silly stipulations that you might have to follow in order to grab your free grub.

Hard Rock Cafe will give you a free Local Legendary Burger, but first you have to literally sing for your supper — specifically, an entire rock song (lyrics will be provided) onstage. Worth it?

Great American Cookies is sweetening Tax Day with one free sugar cookie per customer in stores, no purchase necessary.

McDonald’s customers who buy one Big Mac or Quarter Pounder with Cheese can get another for only a penny.

Pizza Hut is offering free pies … sort of. You have to file a “P-2” form, which asks you, among other questions, to calculate your “Net Pizza Consumption” and submit it for a chance to receive Pizza Hut gift cards in the amount of your net pizza return.

Sonic is offering half-price cheeseburgers all day.

Schlotzsky’s will give away one free small original sandwich (packed with ham, salami, cheddar, black olives and more) per customer with the purchase of a 32-ounce drink and a bag of chips.

California Tortilla is handing out free chips and queso or salsa to anyone who makes a purchase and says the secret password: “Taxes Shmaxes” — the chain prefers that you say it “in a bored, funny voice” to make it more “fun.”

Boston Market fans can grab two meals for the price of one, whether it be a whole sandwich, salad bowl or other entree option.

Sonny’s BBQ is offering half-priced rib dinners (usually $12.50).

BLT Prime & BLT Steak locations are offering half off all alcoholic beverages.

Orange Leaf Frozen Yogurt‘s fans can fill up a container with froyo (up to 16 oz.) and as many toppings as that cup can physically hold for only $4.15. “Like” Orange Leaf on Facebook and claim the offer when it’s posted on April 14 — print the confirmation or show it on your smartphone at the store.
