The cashier at subway played a trick with me, I ordered sandwitch and salad, he said billing machine is having some issue so he will collect the cash, prepare the food card and deduct the amount from it.He charged 430 rs instead of actual billing amount 420 which I overlooked initially. I felt something is not right and added the cost of the items, when I questioned him after finishing the food he said he mistakenly charged me more.But I am sure it was done intentionally as we seldom check and add up the prices, he return me exact change in coins from his pocket without counting. I know I have my own share of fault here by not making the card myself, still you dont expect to be cheated in these malls in this manner.Btw food proportion is also less than other subway joints.
