Keep going despite the hurdles

Imagine a Starbucks cafe where you would have to pick up a cup and
walk past three different baristas, each with its own queue, and
where something else is added to your coffee each time. Imagine that
when you get to the final desk (and chocolate powder added to your
foam) your coffee is cold and you have to pour it away.
This is what happened to me at the flybmi checkin desk at London
Heathrow. I was there 1h15min before departure to Tbilisi. By the
time I had came to the third stage (after the weighing queue, the
electronic boarding pass queue and had moved to the front of the
baggage drop queue) I was told the computer is closed for luggage
despite having been guided by staff first and been issued a valid
boarding card and allocated seat 13D later.
The taste of cold coffee is having to cut my trip short by 3 days (no
other flights to Georgia operate before Wednesday). But when you have
a mission you can't give up because of a bad coffee.
