I've been in airports where to get to gates you do not have to walk through the tax free shop, although you do have to walk by it. The Copenhagen airport you have to walk through it which is also irritating if
1. it is busy because a shop is not as well structured for walking through as a hallway is. The shop is structured for you to look at things and buy.
2. you have a child with ADHD or similar problems which has to be watched because they might break a big bottle of something on accident.
3. You have to navigate a wheelchair or a large pram through the area.
4. This shop is actually very big so there is a lot of tax free shelving to walk around to actually get out to the hallways that take you to the gates.
When you get through security/customs/etc you find yourself on a long wide corridor, which has all the gates on it, and also the entrances to the individual shops.
