Trip report: Tel Aviv

Last week I was told:
- What a co-incidence, 3 companies in Tel Aviv have urgent software performance issue to solve now, could you please fly in ASAP?
- Of course, I love coming to Israel! I'll get there Saturday evening, can we start on Sunday then?
- No, let's make it on Monday, Tuesday, Wednesday.
- OK.

First company: we quickly found the performance issue was caused by a bug in their software they were already aware about, and it was planned to be fixed this week
Second company: After we found the root cause of their performance issue in the first hour of our workshop, I was told that they found it already last week, and now they just wanted to observe how would I find it using out tools. Then we found their next bottleneck, which we can't fix any way.
Third company: One engineer I was supposed to work with was getting married, another got sick, and with their backup I had to spend ~50% of time installing and configuring tools.

P.S. As a mid-winter holiday it was all great, +27C, warm water in Mediterranean and Dead Sea.
