We tip to reward great service, right? Image: William Warby on Flickr. Creative commons licence.

Sajid Javid, the Business Secretary, is launching a consultation on tipping amid concerns that restaurants are confusing customers by not being transparent about the charges and who actually receives any tips.

As part of the plans by Mr Javid, restaurants will be forced by law to give tips paid by customers to their staff.

The Government will force restaurants to say on bills exactly where tips go following concerns that employers were simply keeping the money themselves.

So, why do we tip? And where do these tips go?
