The hoods always look great after Nelbud comes to clean them. There has been messes left by the workers. (Chemicals left splashed on walls the first visit and a messy sink. Along with the brooms and everything not returned to their places. The last visit, that was all good. The mess was that they threw their black gloves everywhere but the trash. On the floor inside, by the dumpster rather than inside the dumpster, in the rocks/decorative areas outside the restaurant.) If they would pick up after themselves properly and leave the store how they found it, it would be perfect.
