I did exactly the same things after my 4am Wal-Mart run, my shoes had outer booties disposal over them and two pairs of gloves entering, one on the way out and zero in the car. 90% isopropyl between. I have had P100 masks since Ebola hit big D in 14 and airtight lab goggles that look like regular glasses since then too. No one blinked an eye to see someone in a mask gloves and booties shopping I wasn’t the only one in a mask. All the packages and bags are in the garage they will all get a 500ppm bleach decontamination later today before coming inside.
Don’t forget to pick up your BL4/chem suits!
