Two separate visits (to the Durham branch), two separate conversations:
Me: Do you have any raspberry canes, please?
Assistant: [Pause] Ermm. No. We do have bamboo canes.

Me: Can you tell me where masking tape is please?

Me: No. Masking tape.
Assistant: Gorilla tape?

The staff in this branch are, basically, shop assistants who don't know anything about DIY, tools, paint or gardening. They have an unhelpful, casual attitude bordering, in some cases, on rudeness; they make you feel that you're being a pest if you ask a question (to which they're almost certain not to know the answer); there seems to be no proper staff supervision or performance management at all. A disgrace; shameful - don't go there if you can go somewhere else.
