I guess I was very lucky.I had a great Scrum Master. 
He was always there for us when we had any impediments.
He was always bringing new ideas to our team. 
My recent impediment was few months ago. 
Since I am working from home I had to
deal with service outage few times. 
I had to work from Starbucks it was fun
luckily I didn't get infected from virus.
