Between 2pm and 5pm, apply coupon code "TWOFORFUN" to avail of this offer online or via the app. I know I will. Sometimes, I like to go to Shake Shack and with a very long straw, drink from others' beverages. When they look around in alarm, I declare, very much like Daniel Plainview, "I DRINK YOUR MILKSHAKE". They usually don't respond. Anyways, I'm not welcome back technically but what are they going to do, call the cops? Ha, I should think not. Offer is not valid for drive-thru purchases, delivery, or curbside. Shop Now
