Complicated Food Order Made Easy

I had a moment's inspiration at the pub today. We were having lunch and everyone was choosing something different. I'm rubbish at remembering orders...then the inspiration.

1. Everyone points at what they want from the menu

2. Take a quick snap

3. Take phone to the bar

4. Give order

5. Job done

Also, as I was paying on my credit card, I have a record of what everyone ordered and how much they owe.
