Not respected as "work"

I've been a shopper for five years. A couple of family & friends have made snide comments that "doing Instacart isn't really work. It's just grocery shopping." Today a friend said "some of us work". I replied, "I work too." The response was "yeah, right." Sure, it's not the same as a traditional job but dammit IT IS work Has anyone else ever experience this disrepect from family/friends?
