Allowing pets in the office is not an inclusive policy.
The Google one is especially reasonable, as they are not allowed on furniture, and anyone can ask people in their area not to bring pets to the office.
However, I'm sure others would have preferred to live with the symptoms to avoid the confrontation. Do you want that to be your colleague's first impression?
I tell them to please not do that (and usually get extremely hostile looks), but again, not everyone would be comfortable with that.
Guess what, me and a number of other people can't work for you now due to a completely work-unrelated medical reason.
And if ventilation is not good, it can ruin my whole week.
Of course not, so maybe it has to be privileged people complaining about this.
