I wrote to Tesco head office about the green point symbol in Tesco packaging. We (my design company) conducted some research on this symbol (a round circle with two ying and yang arrows on it which if on many back of packs). No-one knew what the symbol was.
We told Tesco this and they called me a few days later to say they are removing it from the packaging.
After 9/11 someone wrote to complain about the pack of American rice that showed the twin towers on their packaging. They removed it from sale and we had to redesign it straight away.
If members of the public make a fuss, Tesco will do something. Store managers or employees of Tesco are not treated the same way. I worked for them for 8 years. They are not really a people company. Some nice people work for them, but the company culture is very aggressive and not friendly. Write to them, see what happens.
I felt the same about the boarding up, so i wrote to Tesco via there website about 2 weeks ago, and within 10 minutes of sending the email someone phoned me from Tesco to hear what i had to say. They said the manager is trying to get it sorted, but it does seem weird that this sort of thing takes so long, especially as it makes the area so tardy. I think another email is needed.
