As far as I know, these aren't actual legal laws, just ones I've observed... And no, I'm not in Portugal any more, but I'll keep blogging about it for a bit.
- Department stores and supermarkets larger than SPAR in England are forbidden.
- All pharmacists should look like boutiques.
- Labelling of prices is strictly optional. In pharmacies, it is discouraged. If you really have to label a price, try to make it insignificant, like in the small print under the bar code.
- No pharmacist should sell razor blades or shaving foam. Neither should supermarkets.
- One in ten shops to be given over to the selling of loose leaf tobacco. Such shops should always be a few cm below street level, and are allowed to sell men's magazines on the side.
- There should be lots of police on the streets, often using slow electric transport like golf buggies or Segways.
- Police should always be visible. This is to ensure that tourists feel very safe on the streets - Lisbon has a very low rate of violent crime - while still ensuring that there is a plentiful supply of drugs. I was offered drugs 7 times in two days. Unless "hashish" is Portuguese for "my, that's a nice T-shirt". Or maybe I just looked like I needed them.
- Big brand stores are not allowed, with the following three exceptions: McDonalds, Subway, H&M. Actually H&M aren't a big brand - they're only on the border of my consciousness, and I'm not sure what exactly they do, except for sell vastly overpriced clothes.
- Sandwich shops are allowed to sell alcohol. It was quite interesting to realise that one of the soft drink options was beer.
