I guess big box stores are even worse than I thought. Once I went to one I was unfamiliar with - HUGE plant section. I asked a clerk where the ROSES were, and his brow furrowed. I could see smoke come out from his ears while he tried to process the complicated question "where" and the esoteric, incomprehensible gardening jargon "ROSES". He fumbled around rather than admitting which part of the question was difficult, and then i saw them over his shoulder, where he had been sweeping earlier. Okey-dokey. I guess not everyone can recognize roses or read the word "ROSES" on large pots and labels.
