That is very interesting lonewolf.
I can see where the theater income would be limited - one admission and you can stay as long as you want. There is a porn theater in Hollywood where many of the reviews say it is filled with drug addicts looking for air conditioning who never leave!
But the arcades I would think would be a gold mine. $1 only buys a couple of minutes - keep feeding the machine or get out - use the same videos over and over - so you main expense would be cleaning.
I can imagine the toy sales would be a nice profit - I would much rather go and pay cash and know what I am getting rather than order through the mail. I always think of the cartoon of the box sitting on the doorstep covered in "Dildos R Us" shipping stickers with the caption "they said discrete shipping!"
Luckily out here stores are slowly reopening - some hare reopened their arcades - the theater is still closed. But at least it looks like they will survive. A number of the bath houses have permanently closed.
