Ever had to much to drink and woke up feeling like this?
How do you know you had to much to drink? I guess there is no real way of knowing until you get pulled over.
Why do cops ask you if you have been drinking? It's not like you are going to tell him.
Just tune the cops "excuse me Mr officer sir... my name is bob and I am lost, can you tell me where Voortrekker road is". I am sure this will work out perfectly for you next time.
Try it and let me know how it went down.
