With all the rules and regulations about getting cards for working on site etc, I wondered what are the rules for drinking Alcohol and site work, for example are you allowed to have a pint at lunch time, would you be allowed back on site? I only ask because as you may guess it's been a long time since I worked on a building site, and it was quite common to go for a beer at lunch time, is it stricter these days? would you be chucked off site if someone smelt alcohol on you?
