Smoking ban in UK. One month later

It has been one month since the smoking ban entered into force in the UK. This law, already implemented in other countries has been adopted in different levels, altough always proved to be benefitial for worker's and general public's health.

After this short period, it would be nice to have first opinions and comments from those under this law (employees, employers and general public in the UK), or from others that saw how this law was implemented on their country.

Any opinion is welcome.
