Food items use the method I described above for audio because they're destroyed immediately as their clicked; we need to use on external audio source.

FoodScript.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[System.Serializable]
public class FoodScript : ClickableParent {

	
    public AudioSource Source;
    public AudioClip Clip;
    void Start () {
     	//when the gameobject is created, we find the audiosource on the player so we can use that source
        Source = GameObject.Find("Player").GetComponent<AudioSource>();
	}
	
    public override void OnClick(Vector3 Clickposition)
    {
        Debug.Log("Clicked " + Name + ", Distance: " + Vector3.Distance(Clickposition, transform.position));
        
        if(Vector3.Distance(Clickposition, transform.position) <= MMinimumDistance){
            Master_Manager.current_Hunger_Level += food_Value;
            //Because we're calling Destroy right after playing the audio, we need to use an audiosource on on the gameobject
			//Otherwise, the audio would be interrupted when its destroyed
			Source.PlayOneShot(Clip);
            Destroy(gameObject);
        }
       
    }
}
