Gesture & etiquette
Approach the person at a natural moment (not during focused work); use a relaxed, friendly tone; a light, casual smile signals it's a genuine invitation with no obligation.
よかったら' (yokattara = if you'd like) leaves the option entirely open and avoids putting social pressure on the person to accept — this considerate phrasing is important in Japanese workplaces where people may feel obligated to say yes.
