It screams “I don’t know what I’m doing, and I’m not ready to perform”, IMO.
It’s amateurish and unprofessional.
No it doesn't, and it's not.
Maybe where you are from it's different, but in my area the musicians who play for a living are all playing multiple types of gigs. The Tribute bands, the original band, the cover band.
When they are playing the solo restaurant and winery gig they use the iPad for lyrics.
