Well that was an interesting set of late shifts!!!
6 drink drivers
1 RTC who's female drink driver (I say that in the loosest terms) Was sooooooo Pished I had to -
a) help her out of the car she crashed
b) literally carry her to my car because she could not walk / stand
c) repeat myself at least half a dozen times to be understood (and no it wasn't because of my broad Lancs accent
)
d) she couldn't see very well so when I handed her the breath machine it took her all the time to focus on the tube let alone put it in her mouth.
Any guesses on what she blew

It all depends on how people react to alcohol, the last time I was in that kind of state was VE day in 1994 when I consumed 2 (litre) bottles of Smirnoff's finest.
I did manage to walk to the car when we left the pub, however my vision was so screwed that I saw 3 identical cars side by side in front of me at the first set of lights we pulled up at.
I started upchucking out of the window by the time we were on the A316 and I did end up being carried to bed where I stayed for 3 days with a major headache and constantly vomiting.
In the case of your customer, if she was an average size then I'll stab a guess at around the 140 mark.
