I asked my former boss for some clarification via mail. Given a table, I was supposed to edit some user info in the company system. Had some questions on a few entries only my boss could answer.
Boss would organize a meeting, also inviting a more experienced co-worker I worked with. When the meeting starts, I get to know that my boss will join in a few minutes..... few minutes later, boss cancels the meeting. So it's me and the co-worker, who cannot answer my questions.
A simple mail could've solved it...
