Critiquing Bathroom Ads

This is a recreation of an ad I saw last night.

• 8 oz of Pilsner Lager
  
• 8 oz of stout lager
  
• 1 chilled mug
  
• 1 icy road
  
• 1 pick up truck
  
• 10 hour work day
  
• 1 tired worker
  

Buzzed Driving is Drunk Driving!

Where to start with what is wrong here...

1. You're typical black and tan is made with Guinness and Harp, both are ALES, not lagers. I've never even come across a stout lager.
   
2. You're typical black and tan drinker is not driving a pick up truck. Get them a can of some cheap swill.
   
3. You pour a black and tan in a pint glass (as pictured) or, better yet, in an imperial pint glass. Not a mug.
   
4. And most importantly you never, ever, ever pour a black and tan in a frosted mug! NEVER!
