I needed to buy some sellotape, so I went to McColls, the shop that sells stuff like that and where I get most of my stationary on a regular basis. They usually keep their tape on little hanging displays along with the pens, markers, pencils, drawing pins and other similar items, but I could not see any sellotape hanging there on the display. The closest thing was a roll of tiny tape which had a special little cutter device attatched to it, presumably for people that have trouble using scissors. These things are usually more expensive than normal tape, and you also get less tape, and though there were no prices for the either special tiny tape nor the absent sellotape, I would guess it would be the same deal here.
I was debating whether to a) ask an assistant, b) try again on another day or c) just buy the tiny tape. I was about to go with option c, when an assistant walked around the corner - he was clearly assisting another customer so I decided to wait until they were done and then ask if they have any sellotape or if they don't, what the price is for the tiny tape thing. But as luck would have it, the other customer was also trying to buy sellotape. He asked the assistant if they have any, and the assistant looked at the display, saw that there was none, and apologised. "Sorry," he said, "we're sold out, but we do have this one" and he showed the other customer the tiny tape.
Just then, as I turned about to ask what the price of the tiny tape is, I spotted about 10 rolls of sellotape, but instead of hanging on the display where they were meant to be, they were stacked ON TOP of the display, in the place where nobody ever looks. (Seriously, they were covered in dust and it looked like someone had just left them there and forgot to put them on display.) Pleased with my find, I reached to the top of the display, said "here it is", and took one for myself and gave another to the other customer.
I turned to the assistant to ask the price. The assistant looked embarassed, muttered something and scarpered before I had the chance to say anything. Leaving me and the other customer standing there examining the tape and the display to see if we could find the price on our own. There was no price for sellotape written there at all so in the end we had to go to the cashier to find out the price.
Suck because 1) put your items on display 2) price your items clearly 3) don't tell a customer something is sold out when it isn't and 4) please don't just run off when I'm about to ask you a question.
