Well, you can leave the office at 4pm if you need to. It's also not uncommon to just take one of your 20+ week days off on short notice.
In many cities there are special days (thursday here) where many large and small shops are open until 9pm; one day doesn't break the bank. Big hardware stores, supermarkets and other larger chains are commonly open 9-9 every day. Smaller stores can not do this, and their owners also want normal work hours like you.
