How Risky is a Mall?

How risky is it to be in a mall with an n95 mask? I don't plan on eating or taking it off, just browsing for a ring and maybe clothes shopping. I assume trying on clothes may cause the mask to shift, but I don't expect to be near people and ceilings should be high (at least until I go into a store). I imagine the concern would be ventilation, but don't know what to expect from a large mall or individual shops. If folks could give other activities that are comparably risky, I think that would help put it into perspective for me. In general I have a low risk tolerance (always masking when going out, not eating indoors, etc) and have managed to avoid covid thus far. I'm only considering this since counts in wastewater data has been the lowest it's been for awhile.
