What instantly ruins a burger for you?

@tindrummer for me it ruins most things.

@trollslayer I condiment it much less than while growing up - mostly fries which I eat rarely.

@tindrummer if it is a good properly cooked burger all it needs is good cheese and a quality bun. No other condiments or toppings needed.

@trollslayer opposite for me - mayo, spicy mustard, pickles and purple onions desired additions
