Seems a bit obsessive. Next it will be who smiled at him or who he was introduced to at work.
Yes, it's too much. Some people have more family to buy for and we don't know everyone's financial situation.
A group like that should be drawing names/doing a secret santa. Buying for that many co-workers/friends is crazy imo. If everybody spends 60 dollars to buy her that, in theory she would also spend 60 dollars one each of you. If she just didn't participate period, she could save that money and buy her own Switch?
I buy for my two best friends and immediate family. Thoughtful gifts with a limit. I don't participate in the work gift exchange.
