yes indded!..there's a lot of people who misunderstand the real meaning of ramadan ,someone who falls asleep all day and misses the prayer time as you said and then thinks that he did something good must think again cauz the prayer comes first and before the fasting
..speaking of the bad behaviors , those people aren't good neither in ramadan nor in the ordinary days
fasting to them isn't a worship ..it's some kind of thing wich their parents do and all the muslim nation , something
!!they used to do. so they do and whatever the way they don't care
