lol it's a virus. Wearing a mask doesn't stop it.
You are both correct under certain circumstances and depending on the mask type and proper fitting and wearing of the mask.
EDIT - I have been wearing a mask at Kroger, Lowe's etc. since before the Surgeon General told me not to way back in March. It's easy doesn't bother me.

Dr. Amy Price, a research scientist at Stanford University who was involved in changes to World Health Organization mask guidelines, told Stanford Medicine that masks could impact how far viral particles can travel. The droplets that carry the viral particles are also larger in size than the virus itself, she noted.
"Many people argue that cloth masks can't be effective because they can't filter out viral particles, which are extremely tiny," she said. "Most of these particles leave the mouth and nose in much larger droplets that become smaller through evaporation as they move away from the body. Trapping droplets with the mask means not nearly as many viral particles escape. So, when all parties in a gathering are wearing well-constructed, well-fitting masks, it provides an extra layer of safety for everyone."
The COVID-19 particle is indeed around 0.1 microns in size, but it is always bonded to something larger.
"There is never a naked virus floating in the air or released by people," said Linsey Marr, a professor of civil and environmental engineering at Virginia Tech who specializes in airborne transmission of viruses.
"Breathing and talking generate particles around 1 micron in size, which will be collected by N95 respirator filters with very high efficiency," said Lisa Brosseau, a retired professor of environmental and occupational health sciences who spent her career researching respiratory protection.
Surgical and cloth masks do not protect the wearer from COVID-19 particles as well as medical N95s. (The type of N95 masks used in construction are not effective against the novel coronavirus because they have valves.)
But the CDC does note, "A cloth face covering may not protect the wearer, but it may keep the wearer from spreading the virus to others." By wearing a cloth covering in public, the spread of the virus can be slowed by lessening the transmission to others.
