Hindi softens requests the same way — 'kya aap … sakenge?'
The conditional makes a request feel hypothetical and unpressured, handing the listener room to say no — exactly like Hindi 'kya aap … sakenge?' (would you be able to…?) is gentler than the bare 'karo' (do it). For advice it's the same instinct: 'dovresti' (you should) lands like a caring 'aapko … karna chahiye', while a flat 'devi' (you must) sounds bossy. Default to the conditional with strangers and friends; save the plain present for genuine rules.
