Well that turned out to be a storm in a teacup. No need to have pulled my hair out about it after all.
We were first in line at the consulate, walk in take a seat for a moment. Then when it’s my turn, I briefly explain I’m there about a visa and let them know I made an application yesterday for travel on Monday. They take my passport for 10 mins or so then come back, take my payment and the visa is in my inbox within 30 minutes. They do quickly admonish me and let me know it usually takes 10 days, I wholeheartedly agree then leave while counting my lucky stars.
Still would not recommend the stress and panic caused by this scenario so to anyone reading this, make sure you don’t forget your Chile visas and apply well ahead of time.
Thanks for all the comments and suggestions.
