I do get the impression that the fear of coronavirus and resulting precautions sometimes go far beyond what is rational in Thailand.

I understand the corpse for Thai covid victims is bagged, so whoever places it in the coffin is already at low risk.
After that, they could clean up the handles with alcohol or soap and it would be perfectly safe to handle without wearing any protective gear.

There are other examples of excessive precautions. For instance, most Thai hand sanitizer gel dispensers are either automatic or foot operated. The foot operation is superfluous, as in the second or so in between touching the dispenser and spreading the alcohol gel onto the part of the hand that just touched it, no one is going to catch covid. There are many designs of the foot operated dispensers. With some designs, the metal bracket hides the pump outlet, so if not paying attention, the gel can miss your hands and ejaculate onto your clothing.
