Not sure what the definition of cheap is, does that mean the Rube won't make offers not in your favor or just not offer cheap stuff. This interaction doesn't seem much different than normal to me:
May 2 6:19:33PM Rube I'll give you a Yummy Gruel for one of your Cocktail Shakers. OK?
May 2 6:19:42PM Rube I'll give you a Smelter for one of your Awesome Pots. OK?
May 2 6:19:45PM Rube I'll give you a Krazy Salts for one of your Rookswort Seeds. OK?
May 2 6:19:47PM Rube I'll give you a Cloudberry Daiquiri for one of your Crabato Juices. OK?
I only have so much patience! (4/5)
May 2 6:19:50PM Rube I'll give you a Smelter for one of your Very, Very Stinky Cheese. OK?
Last chance! (5/5)
