I'm sure that there is a logical reason behind not doing this (and my brain is just not having a "logical" day), but wouldn't it be great to have a GREATER task selection that involved products like cream, sugar, etc?
I can just imagine opening that Mystery Task to find ... ... ... 49 CREAM! With fully maxed factory, 7 1/2 minutes per order. Multiply that by 49 and you have a 6 hour task (that you have to be semi-present for, especially if presented with a time limit, BUT it's an EASY task that anyone could do. Some won't like it because of the time spent (but then, what task doesn't have the odd complaint...I've even seen a complaint on a House of Luck task), while others will rejoice at getting something that is still ultimately EASY.
I think a lot more tasks could be created to give more variety. Just a thought.
