not on my new painted walls

i'm sure gym members will have old ones knockin' about in attics and suchlike. Give you a bit of time to find what your after.
Save your walls too

Alternatively, just scream maniacally at the next person to lean a plate against the wall and everyone will be too sh1t scared to go near the walls again

one step ahead of you there i already keep staring at people when they take the plates off machines, people are scared of me any way

Or is that not helpful!?
