This is the first time that I have heard that people gamble on funerals. It's a shame though. Why would anybody do it ?
I only gamble when I am in the mood to have fun and enjoy my lesiure time.
Most of the time I am busy working but when I do get the time to gamble, I enjoy it well.
Gambling in a funeral event is the most insensitive thing one could ever do to me honestly. How can I even imagine that happening. There should always be limit to things we do in life and time for everything. You cannot come and be gambling when you're meant to mourn the dead like what's this?
Gambling is not a bad thing persay but the way people go about it is the most horrific. Gambling during burials or working in a workplace isn't a good practice.
You can't generalized mate, there are countries that could have this as their tradition, so you can't blame them.
Just read it here:
In the Philippines, gambling is not just a pastime, but a way to honor the dead. Betting games, mah jong, and card tables are often set up at Filipino wakes, or paglalamay, where the tradition is to keep a 24-hour vigil over the deceased until the burial. Making wagers at games such as "sakla", the Philippine version of Spanish tarot cards, is particularly common at wakes, because the family of the deceased gets a share of the winnings to help cover funeral expenses.[42]
“It has its functions, it is a way of keeping mourners around,” Randolf David, a sociology professor at the University of the Philippines, told Reuters. Businesses dedicated to operating these games go from one wake to another, David said. He added that small syndicates often operate such games, moving from one wake to another.[43]
