I know it’s been suggested before, but an in app notification that weekend surcharge rates apply would be very useful, especially over long bank holiday weekends, when I presume the surcharge would be applied till Monday midnight UK time (as London forex is closed).
It’s particularly useful for non UK customers who would not necessarily know about UK public holidays, and be caught out with the surcharge being applied. Also if you happen to be half way round the world in a different time zone.
But I suspect Revolut make a decent amount of profit from the surcharge, and it may not make business sense for them. But it would certainly cheer up their customers.
