Yea, usually chilli/spices added just for heat taste like, well, nothing.

Real proper use of chilli/spice for flavour to add flavour and make the food enjoyable is what you want to eat, and is what I also like to eat, and a little sting/tingle of spices also adds to the experience, but full on full sweating pain is something that's not needed. I believe in enjoying food, not being punished while eating it. So I wouldn't have even bothered trying that burger in the first place because of what it sets out to achieve.
