Me and my wife. I’ve experienced this so many times. What you need to do is to keep your cool or calm.
The eye sight of the human eye is amazing – you can still check the ass, while observing the pricing of the stuff around. Try to talk to your wife/girl and speak about certain product. However when it’s pretty obvious that the ass is upfront – and you cannot deny it – just make a note to your beloved and express your indignation.

Also – God gave you eyes to watch with and you’re just watching the menu – you’re not gonna eat it.
Sadly God gave eyes to your wife too – and she’s gonna eat you if you don’t play cool.
