I try to get 100% all upgrades - appliance, food, decor (why dont they have rewards for achieving this?) but as i get closer to that in Muertos decor I find it almost impossible to serve all customers. What's the point of giving options to add more customers but the timer doesnt increase? Essentially the first few additional ones help in your stars but after that it's just a waste of coins and gold. BBB and PP with max decor allows me to serve all customers without boosts. Anyone with similar experience in Muertos or other venues?
