1.2.1. Grouping/Distinction by Location, 1.4. Legibility, 2.1.2. Minimal Actions
A 'Top of Page' button appears at the bottom of each page, hidden and with symbols that imply a double affordance.
Remove this button altogether, since there are very few people who will not scroll and not know how to navigate back to the top. Those people would most likely not use the website to pay their ticket at all.
