They had not intended to be quite so lavish but Hastings couple Wendy Schollum and Shane Simons went to town for son Josh's fifth birthday - spending just over $2300 at Subway on Friday.
The wildly overpriced meal turned out to be down to old fashioned human error after the cashier mistakenly keyed in $2325.10 for the $23 dollar spread while Simons absent-mindedly dialled in his pin.
''My husband paid and being a typical male didn't check the total before entering his pin,'' Schollum said.
Schollum said she was made aware of the overcharge by the Subway Stortford Lodge branch who found the error before the couple's credit card statement was even updated and then tracked them down by checking text orders against the time they paid. They also arranged repayment immediately and offered a free meal for the inconvenience.
"We would really like to make sure people know they really went above and beyond - they could have easily done nothing until we contacted them, but they didn't,'' she said.
''It was a lovely meal - I just wouldn't pay two and a half grand for it,'' Schollum said.
The family did not realise their meal would easily eclipse the cover price for Inflatable World in Napier where they spent the afternoon.
''Shane got a foot long meat ball on roasted garlic with sweet chilli sauce, loads of jalapenos and honey mustard. I got a six inch roasted chicken on Italian herbs and cheese with BBQ and honey mustard.
''They were both meal deals,'' Schollum.
Josh had already had lunch at kindy and the couple wanted to have a lazy lunch and some one-on-one time with the birthday boy before a full-on Saturday with his little sister visiting family and friends to celebrate.
Although Subway alerted them to the error yesterday, Schollum said she would have noticed the whopping charge any way as she is ''the money nazi of the family'', and would have ''checked what could have turned out to be the world's most expensive Subway meal.''
- One of the most expensive sandwiches in the world is thought to be the Bacon Bling, sold at Tangberry's cafe in the resort town of Cheltenham, England. The pricey sanger retails for £150 - or NZ$293 - which represents better value than what Shane paid at Subway. He could have bought nearly eight Bacon Blings for the same price.
