Leaving everything you're doing for salat

Assalamualaikum warahmatullahi wabarakatuhu Please clarify the following facts about salat. In my upbringing I was told that when the iqama is said you have to leave everything you are doing for the prayer but today someone quote an Hadith for me that: >The Prophet (ﷺ) said, "If the Iqama for (`Isha') prayer is proclaimed and supper is served, take your supper first." (Sahih al-Bukhari and other variations in Sahih Muslim , Sahih al-Bukhari and elsewhere) The prophet of Allah said 'if dinner is ready and iqama is said, you should start with the dinner first' So I want to ask is eating food better than praying Jazakumul llahu khayran
