@worldinbetween, WELCOME BACK!
But you have to remember that we are tourists with 3 days to spend (typically), the first 20k note goes for the travel card at 4,150 ft each I think. Instant small change. The ticket windows are always full of cash.
Then each subsequent 20k note is broken::
........Tourist Lunch: 7,000 ft another note broken
........Wife wants to bring home gifts for her sister and parents; bang, 4 20k notes gone
........Funicular for two; another 20k note gone
.........Danube Boat Ride
.........Tourist Dinner
..........Opera Tour
...........Parliament Tour
..........Kadarka's Wine Bar at 4k a bottle
..........Made a wrong turn and ended up walking down Vaci ut.............bang, bang, bang, bang the 20's are flying out of the purse.
...........Grocery Store (for the apartment tourists); now you got a problem.......
By the way thought about trying to contact you when we were in Budapest in June but we were too pooped out from the first half of the trip. We were also thee in March and three trips a year is the limit so we are stranded here until December. Then we will be in Budapest from the 20th of December through the 4th of January. Maybe we can buy you and yours a cup.
