Purchased multiple groupon deals and even without, we've used this restaurant for take out several times (being that it's close to work). Today we ordered delivery from the online mobile order. At check out, you can choose how much gratuity to add. I added the tip and when the man came & delivered the food, all I had to do is sign my name, right? No! He points to the tip line and expected me to write in more. I said "I already did online" (obviously I knew because it changed my total to amount with tip) he yells "no no, add more here". I'm livid!
