to be annoyed by this change of plan?

[Justforlaughs]

3 weeks ago I had a message from work saying that I had to attend a course in Coventry on Wednesday of this week. I arranged child care accordingly. This morning I got a call to say that now the course is in Baldock (an extra hour driving each way) and is now on Tuesday - so I need to try to rearrange childcare at short notice. AIBU to be piss off by this?

Of course YANBU! I would be annoyed at the fact it was an extra hour each way let alone the fact they changed the day too! Some people need to realise how disruptive changing plans last minute can be.
