I just want them to remain seated! Stay in your seat and do NOT move, unless you need the bathroom. It's so, so messy, (and I have no mods, I don't use them). It really does dampen the experience. I have no idea who is sitting with who because they are all walking around the restaurant talking to anyone in sight. Say hello…
My jaw dropped when I realised that they didn't queue at the cash register to pay for their items. C'mon, that's basic. Open for Business was my favourite EP in TS2 so I was very disappointed too. I wish they didn't combine two EPs like they did, bad idea in my opinion.
I found a few, there's GameStop: http://www.gamestop.com/pc/games/the-sims-4-get-to-work/120142 There is also Amazon.com - http://www.amazon.com/Sims-4-Get-Work-Mac/dp/B00T3MEQNI/ref=sr_1_1?ie=UTF8&qid=1423526498&sr=8-1&keywords=Sims+4+get+to+work
