I was in the minefield, minding my business. There was a cat around, setting off mines and stuff. So, to ensure my safety, I decided to dump dangerous stuff out of my inventory. For example, bottle of sulphuric acid. Mellis had gifted it to me, but it spilling all over me would have been really bad situation.
So I pressed D, selected sulphuric acid and got rid of it.
Final score was 5002.
