I see all the 'I GOT TRICKED INTO EATING OATMEAL RAISIN' and I wonder how people can confuse Oatmeal raisin and chocolate chip - they don't look that similar.
but the biggest diff is the chips are brown (unless you're using really dark chocolate) and sticks out, while raisins are half-buried or mostly covered by dough.
quinn would consider that a pleasant surprise
