Susan Edwards, 69, from Westerhope, Newcastle upon Tyne, said her seven-night stay at the Lido Corfu Sun Hotel on the Greek island was the "worst holiday" she'd ever been on.
She told Chronicle Live there was "no English food" on the all-inclusive menu and she was "sick to death of looking at rice" by the end.
The grumbling gran was also dismayed at only being offered chips "one day out of the whole lot" during her £750pp week-long stay.
Now the hotel's manager, Makis Triantafyllos, has hit back - alleging Susan's complaints were a ruse to claw money back.
He told The Sun: "From the very beginning of her stay, [Susan] demonstrated clear intent to fabricate complaints in pursuit of financial compensation, going as far as to complain about the weather."
He alleged she demanded to know from the staff: "Why is it raining?"
The manager claimed Susan's attitude had been "sarcastic and dismissive" to staff who did their best to accommodate her.
The hotelier also fiercely defended the menu, saying the food service is "generous and diverse, offering fresh salads, fruits, hot and cold dishes daily".
He fumed that Susan's account of the food was "entirely false and disrespectful to our culinary staff".
And as for the "no English food" dig - Makis said the Sun Hotel offers "world-renowned and beloved Mediterranean cuisine" with other options tailored to guests' preferences - including those from the UK.
The spat continued over the issue of room keys.
Susan said she'd asked for a second key for her daughter because she herself gets tired in the afternoons and likes to pop back for a lie down.
She said the hotel told her: "No, too expensive."
