We cope just fine with variable tax rates and rules for who pays tax in the UK. The general rule is that all prices are inclusive of VAT (sales tax), if you’re VAT exempt as is the case for many businesses then you claim that money back. Some businesses allow you to provide proof of VAT exemption and sell at the price before tax to avoid having to claim back. For things that don’t have different VAT rates, such as food or children’s clothing, it’s the retailers responsibility to price that in - most people probably couldn’t even tell you which particular goods are VAT exempt.
