I do have a proper visa!

Question: How do you get to know the difference between O and 0? Answer: File for a visa to the USA and try to put in your passport number and then try to file it in the boarding pass for your flight!
Early this morning Susan and I went to Schiphol Airport in Amsterdam knowing that she has a boarding pass and I didn't. The person on the helpline yesterday told us "Oh no, nothing to worry about!" but that exactly starts to make you worry about it! Well, the person at check-in at Schiphol said I misspelled the Zero for a letter O in my application form for my visa and I need to apply for a new visa right now, using my mobile phone and pay with my credit card.
So we tried - energy level rising a bit - but it didn't work - energy level rising more - didn't make it easier to push the right things on my small device - energy level up full speed - then I remembered going through this difficult application form for ESTA in November last year and I went back to the check-in desk asking, no begging the person to please check again because I DO HAVE A PROPER VISA.
And he gracefully checked again - and there you go, my passport number was misspelled on the boarding pass only and he could correct it in a second and done! Energy level bursting and calming down. But only after I saw him putting baggage labels for San Franzisco on both of our backpacks.
And right know we enjoy each others company while waiting in sunny Copenhagen for our connecting flight!
