I hope we as Catholics realize how horribly spoiled we are, as regards the length of Mass. Your typical Sunday Mass, whether OF or EF, typically runs something like an hour and 10 minutes at the very least. That is not a long church service at all. Daily Mass, without music (except perhaps for a couple of a cappella verses sung by the congregation), can be over in a half-hour easily. Most Christian denominations have much longer services. In some more fundamentalist denominations, as well as African American churches, there is more than one service, and it’s pretty much an all-day commitment. Can you imagine how Catholics, in the main, would react if they were expected to go to Mass on Sunday morning, then return later on that evening for another liturgy and sermon? There is also Sunday School to consider, which has no direct Catholic equivalent (CCD is “kinda-sorta” Sunday School, and some parishes have Bible study, but the latter is not common).
Catholic requirements for divine worship are very lenient. As I tell my family, God gives you 168 hours per week, the least you can do, is to give Him back one of those hours (really, two hours, by the time you drive there and back, get parked, visit with fellow parishioners on the way out, and so on). And keep in mind, that Mass is not a “social event” — we do not go there to see other people, nor to “fellowship” with them (that’s a noun, not a verb, but I’m just following common usage) unless we just want to, and extended conversations before Mass are just not a “Catholic thing”. It took me quite a while to comprehend why Catholics seemed rather aloof and taciturn before Mass — in all honesty, I thought they were just being jerks! This was when I was a teenager and the Catholic world was totally new to me.
