Don't be scared to ask for extra toppings/syrups or to go back if your drink isn't served the way it should. Remember: you pay to be treated as a king!
There's no wifi because the station offers it at a small fee. Buy access at the place where they sell train tickets, please don't rant to the staff about it, they can't do anything about it.
You have no reason to go to starbucks in Ghent with all these great coffee bars around you, but if you do just skip your usual caramel machiatto and ask for a vanilla machiatto or iced vanilla latte!
Damn expensive for coffee that flat. Decadent choices, if you enjoy overpriced snacks. For just want coffee, there's a better shop literally right next to it. Staff's wonderful though.
