The website will know where you are from based on your IP adress, unless you use a VPN. Only reason they want to "know your location" is to gain access to your GPS in the device if available, to get precise coordinate information.
That then can be used for benign purposes in case of a well secured E-shop or dangerous purposes if the website is sussy
You know what I really like? Badly-made automated translations from a language that I've been learning for 25 years.
For real though, I had to set my browser's language to English so sites like YouTube stop mangling the video titles, like what's even the point of translating the titles when their content isn't translated anyway?
And then there is this piece of garbage site foodnetwork.com. I once wanted to read a recipe there, but the site decided that since I'm in Poland, I should be on foodnetwork.pl. On a frontpage, that is. No way to stay on the English site, and that recipe doesn't exist on the Polish one.
