I had set aside most of my day to walk this grad student from another lab through our sequencing prep protocol, but when she made her sample dilutions she ended up using a plate made for 100 ul samples unstead of 200 ul, so the liquid was partially touching the plate seal in almost every well 😭 very understandable mistake but I had to push past my often-misguided urge to just go ahead and see if it works and be like...ok actually this is a time-consuming protocol that uses expensive reagents and if there's cross-sample contamination at this step we will literally never be able to untangle it completely. so. go do the dilutions again and we'll try another day.
