Meta description not showing as per view source on Google results

[imrubbish]

On our website recyclingbins.co.uk the meta decsription of the homepage under view source is - Recycling bins offers the largest range of recycling bins for schools, homes, offices and other venues. With free delivery on everything and lowest prices guaranteed.
But if you searched for our website in Google the meta description it shows is: Offers recycling binsfor offices, schools and the home.

Someone has already suggested it must be cached. I do not think this could be possible as we are fairly regularly crawled and it has been like this for weeks and weeks. No one seems to have much idea. could you possibly share any light?

I am not concerned from an SEO perspective, but more from a click through perspective.Thank youJon

Often times, Google views the meta description as more of a suggestion than a command. They'll show a different snippet depending on your search query, and there's really nothing you can do about it. Same for the title tag, they'll even change what shows in the SERPs for huge companies like Apple.

Spot on.  Give her the "Good Answer" click, my friend.  No one could have said it better.
