It is a healthyI am sure that is a thread about Tescos and that there is a dedicated thread discussing the decline of the High Street and physical retail.
Clearly Tesco wasn’t the next (or the next or even the next or the next after that) so until it obliges by going down the pan it seems not unreasonable to discuss other retail businesses that are actually (or likely to be) the next down the pan.
The other option would have been to read @exbluejob ‘s musings, perhaps offer an opinion (the OP didn’t actually ask a question so obviously didn’t require any definitive answers) and then let the thread lie dormant for however many years it is before Tesco croaks.
With a lot of big name companies going to the wall I wonder if Tesco is in the firing line. Closed down Tesco direct, got an email yesterday saying the Tesco Wine By The Case is closing. Our local (very large) Tesco seems to have a lot of fairly empty shelves, made me wonder.
