The answer is: teaspoons. That's right, a pack of teaspoon.
Yvette Whelan was frustrated that his stepson Liam and his brother kept on losing her teaspoons, so she sent him to a local market to buy a pack of teaspoons.
But staff at Tesco in Haslingden refused to sell the pack of teaspoons to Liam because he was under the age of 18.
"Knives, forks I can understand but teaspoons? No," Yvette said to the BBC, "There's just no common sense." Liam had to go home empty handed and was "really embarrassed" by the incident, she added.
Tesco later apologized for the incident, saying "We do include a till prompt for proof of age on our self-service tills for some items. We ask our colleagues to use their judgment as to whether this should be applied. In this instance, this was not followed and we apologized to our customer for any inconvenience caused."
