I always say no because receipts have been shown to commonly contain BPA and other cancer-causing/endocrine-disrupting chemicals that can be absorbed through your skin. The data seems to be mixed on whether or not the dermal uptake is significant enough to pose a threat, but I just don’t want to take the chance.
If you have to have a receipt, try to touch it for the least amount of time possible, avoid touching the printed side, and keep it in a container or Ziploc bag in your main bag or somewhere else.

Even though they’re not traditional shooters, the Ratchet and Clank games are really fun. There’s a pretty big genre difference in the games in the franchise, with generally the earlier games being more platform-ey, especially 1 & 2. A lot of the humor from the original trilogy still holds up today.
There’s definitely some “unfun” parts in the games (giant mech fight from rac2 and the hacker from rac3 come to mind) but overall cozy imo. Some of the most unique and fun guns in any game.
If you’re looking for strictly more shooter, check out Ratchet Deadlocked. There’s barely any platforming and no mini games that I can remember, it’s pretty much all shooting. NG+ makes it super cozy. It’s really nice to play emulated.
