The egg in the picture is so small it has been described as coming from a hummingbird while the rasher could be from a micropig. Together, the ingredients are lost in a large, apparently unbuttered roll.
The anonymous poster took to social media to share the picture, commenting: “This is what a £3.20 bacon and egg roll from Edinburgh Airport looks like.”
The traveller - username “spambox” - wrote that he bought the snack at EAT, a popular cafe chain.
He added: “I never asked for a refund as I figured it must just be overpriced s*** cause it’s an airport.”
“The part that made it worse was that they told me to take a seat and they’d bring it over.
“The only empty table was clearly empty because it hadn’t been cleaned for what appeared to be weeks and then after 15 minutes I had to go back and ask where my roll was which they had totally forgotten about.”
In spite of his outrage, other online commenters were quick to see the funny side of his misfortune.
One said: “What are they using, hummingbird eggs?”
Others chimed in, adding: “The yolk actually looks like it’s been painted on.”
Some other commenters shared their own stories of airport catering disappointments.
One complained about getting a “rock solid” baguette from a catering outlet. Another claimed sandwiches at Edinburgh Airport are “generally poor”.
“Thereds2015” wrote: “Wow. How badly do airports get their catering wrong? This trend seems to be pretty widespread.”
Some also pointed out that the airport location could be to blame for the poor value for money, commenting: “It is airport food. What did you expect?”
A spokesman from Edinburgh Airport said: “We work closely with all of our food and beverage providers to ensure we offer customers the best choice of refreshments and service.
“Sadly on this occasion we fell below the mark and offer our apologies to this customer. Clearly this is not the service we should be providing and we will be addressing this complaint with EAT.”
