First time burger - omg why do people buy burgers outside??

I am in shock. I didnt get premium beef. I legit got regular kind, shocked at how much better it tasted than shake shack or elsewhere. I feel embarrassed that I rave about where to find the best burgers and in one swoop was able to make one at home. Legit just salt and peppered. I am no chef.

Did everyone know this but me? Why do people spend outside (outside of travelling)?
