A Sydney man is stunned by his café bill – and it highlights a worrying upward trend in Australia.

A Sydney man has slammed a cafe for adding two extra charges to his order, saying the extra charges were “not mentioned anywhere”.

The sandwich from Kosta’s Takeaway in Rosebery cost $18.50, but with surcharges it ended up being $21.27.

These included a $2.55 weekend surcharge and a 1.2 percent card fee for a total of 22 cents.

Complaining about the allegations on Reddit, the man wrote: “I was surprised by the notification on my phone that I was charged $21.27.

“The price on the menu is high, but the total amount was too high.

“I came back after I finished eating and the guy said they had a surcharge for the weekend.”

The shopper said the total cost of his sandwich surprised him because the two surcharges were “not mentioned.”

“Nowhere, not on the menu, not on the board, not at the checkout, is there any mention of a weekend surcharge or card.

“Almost $3 in hidden surcharges for one sandwich is just bullshit.”

The sandwich customer was charged a weekend surcharge and a 1.2% credit card fee.

The client believes that due to the popularity of the Square payment system, it is more difficult for customers to see the amount they will be charged because there is no screen in front of them.

The man also expressed concern about the store’s payment terminal, noting that it did not have a screen to show the total amount before paying.

The Australian Competition and Consumer Commission says businesses are legally allowed to charge surcharges on weekends and public holidays, as long as the surcharges are clearly visible to customers.

“They do not need to include this fee in the total price of their products as the statutory exemption applies,” it said.

“However, if they charge such a surcharge, they must include the following words on the menu: “A surcharge of (percentage) will be charged on (day or days).”

“These words should be as prominent as the most prominent price on the menu.”

The ACCC said customers should be aware of any additional charges before ordering, and if they are not shown on the menu they should be “displayed in some other visible way”.
