I just think it's just good practice to remain humble, and consider that the people who own a giant tinned cat food packaging line just might know more about tinning cat food than you do, with your degree in maths, and frame the question as 'why do you not optimise to the minimum packing material?' rather than 'you should optimise to the minimum packing material'. I personally find that approaching problems with an attitude of "Why do you do it like that instead of like this?", or even "have you considered this?", usually provides more insight and a more collaborative discussion than "You should do it like this".
